Can you give me an idea if aI have a circulation or pinched nerve; maybe some other problem that my symptoms are all related?

I have right hand tingling (mostly when sleeping, relaxing,anything non-active), right 2nd finger at the top joint in pain when bending, lower right upper buttock pain and right foot middle toe w/lower joint cramping (mostly when wearing any shoe & walking more than 35 min). Any ideas if all related? I am pretty active. I am never/very rarely even get a cold, so I don't have a doctor.
