How does chemo cause weak legs?

Many people have commented about weak legs caused by chemo but I haven't found what is actually occurring to make the legs weak. I finished 7 r-chop treatments for NHL in October 2010. My guess to the weakness problem is nerve damage since my feet are still pretty numb. It doesn't make sense to me that my legs are weakest after sitting or laying down, but after I walk around a bit they get much more normal. The weakest my legs feel is when I get up at night to use the bathroom. I would like to know what is going on with these goofy legs.

This is just my opinion and you know what they say about opinions,they are like A******* and everybody has one. I think it is that all our muscles which are controlled by the nervous system are weakened by the chemo,but our legs show it the most because they are what support all the weight.I even had trouble opening twist off soda caps.Even had a problem with picking up anything that weighed more than 20 lbs. It felt like a ton.I went thru the same thing with my legs during and after chemo for about 5 weeks.My feet were not numb,but did feel different. I feel all is back to near normal now. It will take a little time. Remember we are all different in the way we react to the chemo. John

Thanks for the reply. Sometimes I think if I understand all the fun stuff chemo does to you it will make things better. I asked the onc why if parts of my feet and toes are numb then why do the bottoms of my feet hurt when I walk barefoot on a hard floor. He said something about pain nerves and feeling nerves being damaged from chemo that I really didn't understand. So that information didn't make anything better so understanding the leg weakness won't change anything either. Going forward I need to accept my new flaws as my normal condition and work with it. I still reserve the right to complain about it whenever I can get someone to listen. Bob

Nobody looks at them as complaints,only concerns. We all have them. The chemo does different things to different people. We are all concerned about the way it has affected us and are just asking if anyone else has the same effects.Some of the effects are universal.The tiredness being the main one.So far I have not seen any permanent problems. Most have gradually gone away and hopefully you will see the same results in time. Take care. John(FNHL-1-4A-5/10)

Hi Bob,
I finished CVP-R chemo on Dec. 14th with minimal damage. A few toes and fingers were numb, but gradually came back to feeling normal. However...the weak legs feeling is still hanging on. My upper body has gained strength back, but my legs still get weak when I go up and down stairs or stand on them for very long. My knees seem to lock up(which never happened before chemo) and my left hip gets sore and achey come evening time. That was the hip my BMB was done on, and it hasn't been right since. My ONC says it's age related...maybe?...I'm 60.. but I'm leaning more towards chemo being the culprit. The year "before" chemo I could take the stairs 2 at a time, no problem. My hips never hurt and my energy level was great. So...can just one year of ageing deteriorate someone that fast?...I think not. Like you said..we have to learn to live with this "new normal", but we don't have to like it, and it's perfectly ok to complain about it.This is a great bunch of listeners here, so keep coming back.
Take care...Sue (FNHL-2-3A-6/10)

It's really nice knowing there is a place to go where people understand what your talking about. Very grateful.

My last chemo (COP-R) was finished in Feb '09 and subsequent maint. therapy with "R" was terminated in Jan '10 due to inflammation/ulcers inside my throat. I was told that this was due to my reduced immune system, probably by over-treatment with "R". The only medication for this recurring ulcers was Prednisone 60 mg/day which was gradually reduced in strength over a period of time. Everytime the dosage went below 30 mg/day, the ulcers returned with full vengence making eating impossible even in liquid form and I have to go back to 60 mg dosage. More than a year now the cycle of high and medium dosage continued till I found a herb that made the reduction of Prednisone level to 1.25 mg now (expected zero within 2-3 weeks), sucessfully within 3 months.

For past few weeks after the Prednisone level was below 5 mg, I could feel the weak legs when I get up (only starting trouble). My observation is that Prednisone is causing the weakness, but as long as you are high in Prednisone, you will not experience it. Probably the same is happening after chemo cycle when Prednisone is stopped. Doctor told me that the weakness will go away - hope it is true.

Hi Sue, Thanks for the reply to Bob, I share the same symptoms. I finished up treatments last November and thought I would be back to normal by now. I do feel ok, except for the weakness and neuropathy in my feet and legs. Sometimes I have to crawl up the steps and getting up and down my knees hurt so bad. I have started Physical Therapy and it is helping. I also have Menieres disease and have to depend on my muscles to walk. You might want to get your doctor to order you some PT it might help. Thanks for sharing.

Bob, I certainly can relate to those weak legs. When i came up here to my office, it felt like I was never going to make it to the top of the stairs. My legs are so weak, and the neuropathy in my feet just adds to the experience. I had Hodgkins Lymphoma in 2009, finished up Chemo ABVD 7/2010 and radiation 11/2010. The bad part is my legs seem to be getting worse, when I was hoping in time they would get better. I started on Physical Therapy a couple of weeks ago and it is helpiong to some degree, I am actually standing up now when I climb the stairs instead of crawling. I too would like to know what was in the meds that caused our muscles and joints to give out on us. Everyone tells me it is just arthritis and old age. Grant you I am not a spring chicken, I am 63, which is old but today I am as young as I will ever be and was hoping I had some life left in this body. You may want to try PT and see if it helps, if you learn of anything please share with us. Hope you will gain your strength back soon.

This is one Hodgkin's survivor who also has weak legs. I've always blamed it on my crookedness (poor blood circulation in the hip joints). Sometimes its a struggle to get off the floor without any assistance. I do exercise to try and strengthen my legs but I do have my limitations too.

Interesting comments because I haven't heard of anyone else like this before.

Dear Phoenix,

I wouldn't even attempt to go on the floor. My issues are my right knee,
and right hip. Ever since having a bone marrow biopsy, my right hip
has never been the same. Sometimes, I walk a bit like a drunken sailor.
I carry a cane just in case my balance for the day is a bit off.

Since I belong to a club, I do lots of swimming and participate in the
pool exercises that we have each day.

Supposely, my NHL is gone, as of Jan 2011. If the cancer doesn't return, I
will be thankful for some of the side effects of the BMB. I was only
treated with Rituxan, no side effects. Is there some way you can go swimming
where you live??? You can exercise in the water, which is the least amount
of strain to your legs and hips.

God Bless, and continue with your remission. Maggie

During chemo I told the doctor in the evenings it felt like there were snakes in my legs. Alot of muscle pain and tense muscles. She didn't give much that I could do to resolve unfortunately. It has gotten somewhat better (done with chemo 8 mos now). Still have some side effects, but hoping they will go away!

Hi all,
Just finished 6 3-week bouts of R CHOP. Loved every minute of it - not.
I'd have to admit to being a bum for 18 weeks. When tired, I took naps. and only left the house for shopping trips 3-4 times a week. No wonder my legs and knees are weak. The timing of this side affect is odd though. I didn't notice this problem until the very last week. Anytime I bend my knees, its like there is no muscle there to hold them at a slight bend. Steps are the real danger - I can't carry things down stairs anymore, I hold on to railings just in case the knees give out. Stepping off curbs - bad news too. I started stairmaster'ing today, and doing leg extensions and leg curls with tiny weights. Yea, muscles are gone. Hopefully, they will come back. Good luck to everyone out there.

My guess wold be neuropathy is adding to your sense of leg weakness, if you have it. I got neuropathy pretty badly from my drug combo (different chemo from yours). Vinblastine caused mine, but many other drugs which work similiarly cause neuropathy also. I was part of a clinical trial regarding a cream to treat residual neuropathy, but the stuff did me no good at all.

There are a variety of ways the neuropathy experience can go. Some people never get any, some get it bad, and some get it terribly (I have heard of cases in which it made the perosn's whole body numb). When actively on chemo, my legs stayed numb at least to the knee, and my hands past the wrist.

Some people get over this rapidly and completely, some partially, and some do not recover much at all. Over two years since treatment, I would say I have recovered about 50% of the feeling in my hands, and a little less than that in my feet.

I hope your neuropathy goes away rapidly and completely !
