Please be checked out by a good doctor. The numbness in my hands was caused by carpal tunnel. After surgery on both, I no longer get that numbness, unless I do something too long of course. Are you having more hand problems in the summer, is it hot and humid where you live? Two summers I had horrible pain and what felt like swelling in my hands. I assumed it was caused by arthritis. Turns out it was fibro rearing it's ugly head-increase in Lyrica solved the problem for me.
Please see a doctor to figure out what is the problem.
