Gee thats odd, I have had a tingling, numbing feeling in my right pinkie toe for the last year! I still don't know why it occurred, but am thinking perhaps I injured it without paying attention, and maybe did damage to a small nerve. Hmmm, now you have me thinking....lately I was on a drug that gave me bad side effects while I was being weaned off. My right top of the foot and lower shin now also have that same feeling and I always thought it was just one of the effects causing the strange sensation. Maybe this really IS nerve damage and is travelling?
Once, a long time ago, I had tingling in my big toe that eventually became numbness and hip pain. I went and had some xrays showing all was well. The doctor prescribed some back exercises (which actually strengthened the abs which aligns the back) and within a short time all was back to normal. I was about 28 then. It might take longer to return to normal if your husband is older.
