Poss return of carpal tunnel issue in left hand

I have been experiencing very dead hands at night for last 6-8 weeks but thought at first it may have been a neck issue as also occasional headaches. I have been having treatment from osteopath for it. Now I am having ‘stabbing pains’ going down left middle finger and sometimes first finger. Also a dull ache in wrist. This with a loss of grip/power in left hand makes me think my last injection has worn off. It can happen when I am not doing anything at all, but definitely happens if I have been knitting or sewing, gardening and peeling vegetables.

Many thanks
