<s>[INST] Hi, I have had tingling and partial numbness in my fingers of R hand for about 1 week, now has extended to entire R arm. Possible pinched nerve? Had some pain in back (typical for me due to ongoing back issues, slightly more than usual) now decreased, but numbness, tingling in limb remains. [/INST] hi  It is quite possible to have a pinched nerve in your neck, going by the description. I suggest MRI of the neck to confirm the diagnosis. Start pain killers , muscle relaxants , pregabalin and physiotherapy in the meantime.Dr Gopal Goel ,Orthopedic Surgeon </s>
