Welcome to the forum Alim!!
As Sherrine said only you doctor can really tell for sure. I truly hope you don't have FMS. But if you do you've found a great site to learn and get support from.
I have alot of problems with my hands and feet. Fatigue is always lurking around and occassionally gets the best of me.
It took me about 10 years to finally get my diagnosis, partly because I preferred being in denial and because I didn't think there was a doctor out there that would support my findings. Since I've gotten on my meds, I'm doing better. I hope you can get proper med soon too.
Keep in touch and let us know how you're doing.
Take care,
