Seems it's probable that I have carpal tunnel syndrome and have to go for nerve conduction tests (deep joy!). I know it is linked to hypothyroidism, but as my results show optimum levels - TSH less than 0.5 and T4 at high end of range - I am at a loss as to why I have it. I am on 100mcg Levo and B12 jabs. Just had bloods done for ferri tin, folate. Any ideas gratefully received.
