2 years ago I was running my startup Tennis Buddy, and everything was fine when I got pins and needles pain one morning all over my body and blurred vision.
I have had this a lot of times before in my life (around 20 times), and it always went away with rest within 1 week with no problems. However, this time I was in the middle of finishing a contract and didn't take rest. A couple of days later, I reduced work lod to become better, however it seems like it was too late, since the pins and needles pain just didn't go away anymore.
After a month of still not getting much better, I went to see doctors, however they could not find anything. There was the assumption that it was psychological, however, I just don't have any symptoms of depression.
During that time, I noticed that only very little exercise (running for 1 min) increases the pins and needle pain for several days or even weeks. Then for the next year, I tried to not exert myself at all and stopped all work to get better. This did reduce the symptoms, however, just small exertion triggers the symptoms again. After this happening a couple of times, I also got strong muscle twitches (several thousand per minute sometimes) all over my body.
There was also the assumption that I had CFS, however, it does not fit, since I just have no fatigue at all, I only have constant nerve pain/pins and needles, blurred vision and muscle twitches.
I also moved back to my parents and had to leave my friends, so it's getting really difficult for me to stay positive. Please let me know any advice that you might have.
