I'm not 100% sure I dealt with what you're describing, but I went through a period where my left foot and hand seemed weak and clumsy and detached from my body.
I saw a neurologist a couple of times. He wasn't concerned. I'm guessing I had nothing wrong because it eventually got better. I do still feel it now and then but I don't know if it's stress, fatigue, pinched nerves, etc. But I doubt it's anything serious because it's been a year or so and nothing's gotten worse.
Iīve seen a couple of neurologists and they all seem convinced that I suffer from functional symptoms due to a conversion disorder. But the problem is that the symptoms gradually has gotten worse over a couple of years (a year ago since last neuro exam). I have the clumsy feeling and intermittent slowness and coordination problems, and on top of that I have developed a tremor (most left hand, but itīs there in both hands).
I would be lying to myself if I were to say that I canīt see the presence of anxiety in my daily life, but I just canīt shake this feeling that there is more to it. According to my former neurologist though, the thing with conversion disorders is that they both (a) get worse over time if not treated correctly and (b) tend to mimic the things one fear the most.
I guess my lifestyle could be catching up with me, and my lack of physical activities/daily walks and unhealthy eating/sleeping/caffeine-habbits could also contribute to this. On top of that this period of the year marks the two year "anniversary" of my fathers death, and his struggle against an extremely agressive form of plasma cell leukemia. I think that plays a very big role in my HOCD to be honest. But, given what I saw cancer do to a man I loved more than life itself, I would have thought that cancer would be the focus of my OCD. Not Parkinsonīs, which I have absolutelly no first-hand experience of (not family, not even the older population of my family).
Thatīs what keeps bugging me; why would I develop symptoms of a disease which I previously knew nothing about?
