Hi Bill. My stroke 3 1/2 years ago completely paralyzed my left side. Slowly, the feeling came back. I had electrotherapy and occupational & physical therapy 3 times a day for 3 weeks–then 2 times a week for several months after I came home.(I went to a therapy center.) Even though my left hand and arm felt like it weighed 100 lbs. to lift, I made myself used it all the time. I bought little 1, then 2-lb. hand weights and practiced with them. All this therapy brought back more feeling and dexterity. At one time I couldn’t move my left hand. Now I play piano and ukelele. But it took a lot of effort, therapy and time. If you can get therapy, it’s well worth it. If not, look up exercises on the net and work at home yourself. You can buy tens units (for electircal stimulation) on the net. Check with your neurologist if that might help you. Don’t over-do. During therapy they had me do 10 repetitions 3 times for each exercise. Your situation may be different, since I had paralysis, and you have numbness, but maybe some therapy would still help.
