Radiation Induced Plexopathy

I too am a long term cancer survivor. I had colon cancer 24 years ago followed with radiation treatment. Was wondering if anyone else has been diagnosed with radiation induced plexopathy, your symptoms and any treatment/solutions you might have. My symptoms are; muscle twitching, deep aching, tightening feeling, buzzing in my legs from my hip area all they way down to my toes. It's a little more tolerable during the day when I'm busy but the minute I sit down for any length of time, it starts in and at times is pretty awful. Trying to get to sleep at night is the worst. I've seen a Neurologist who put me on gabapentin but I just don't feel it's really helping all that much and from what I can gather so far, there isn't really a lot of help out there for this. I also see an acupuncturist which does help a little bit but not for very long. I've very thankful I'm here today but having some relief from this would be really nice too. Thanks, Barb
