Worries about health 6 months after surgery

Hello everyone! I have learned a lot from reading your posts since my own experiences with kidney cancer began and finally found the courage to join you all a few days ago.

My own kidney cancer journey began several months ago when an ultrasound revealed a small mass on my kidney. The mass turned out to be a 1.2cm clear cell tumor which was taken out using the robotic laparoscopy. I spent some time healing and went back to work hoping that I could get on with things, but lately my body has started to show some unusual symptoms and it is all now playing on my nerves a lot.

I have had a weakness in my arm for a number of years and despite going to hospitals never managed to find out what was causing it. Those symptoms are still with me. I also have a weak leg on the same side of the body, but put it down to a sports injury I got many years ago. Several weeks ago though, I felt tired in the evening and decided to take a picture to see if everything was okay. It wasn't okay. There was an obvious sign of ptsosis in one of my eyes, the same side that my general weakness was on. Sometimes you barely notice it, but at other times it looks really odd. All my checks are now done at the same hospital and I have tried to get to the bottom of it, but it is taking time and I am seeing different departments. The weakness is only one side of my body.

The opthamologists have done checks and think it may be myasthenia gravis. At the back of my mind though, I am worried that it may be something connected to my original cancer diagnosis. I recently had a very bad cold and several weeks later my voice is still weak. Again, that could be a symptom of MG, but I have also read that my symptoms are similar to people diagnosed with lung cancer and my other concern is that it might be the brain. The stress means I am not sleeping very well lately and so my mind is enveloped in a sheet of fog and so I am not sure that my brain is okay! I see the nerve/brain specialist next week. I am also seeing a doctor about my arm. The nerve tests show no abnormalities.

I also checked my thyroid as I read that there can be a connection between the thyroid and ptosis, but my results showed nothing related to that. What they did show however was a liver reading that was unusually high and saw me transferred to an internal organs specialist. They think it is nothing serious, but I have an ultrasound and more blood tests to check further. It is unusual because I no longer drink having had cancer and even when I did drink my readings were always fine.

I have also had my first follow up checks for my RCC and of course that is really, really important, but I seem to have a whirlwind of things going on and I am getting a bit depressed by it all. I am really worried by it all. I thought a small tumor would be relatively easy going in the great scheme of things and had no idea all these other things would be going on. I have spent a lot of time in the hospital lately and don't seem to able to get any answers yet.

Am I panicking too much? And what is the best way to handle the stress? I find it hard to do anything but try to get to the bottom of what is going on and so my mind is hyperactive trying to put the dots together as I worry that MG is overlooking the possibility of cancer. MG would be very bad, but probably quite manageable. The alternative is something much more unpredictable and intimidating. I get the results of my first follow up kidney tests next week. It's not easy.
