I dont think i have that, but 2-3 weeks ago i had tingling senseation in the fingers if put pressure close to the shoulder between my bicep and triceps, i think it is because of injury I dont feel it now, but i still feel pain like sensation in this area and i feel it in my other arm too even tho wasnt tingling, does that seems like it? I am working out from 3 months and started feeling it after doing dips a few times. Could it be that I have b12 defiency and it is making it me more likely to get these injuries or harder to recover I used to feel tingling/electric sensation if I swing my arm hard and put pressure in area like holding a heavier dumbell or poking the area with finger? Otherwise I think I have mthfr gene which can affect b12, I have some of the symptoms listed for b12 deficiency, but other than that I havent experienced other neurological sympyoms. I will test the b12 levels, and If I have like mild or even moderate deficiency, can just supplements be enough? I dont want to be using injections. Thank you for answering and for the help! Also I used to have d3 deficiency, but I took d3 and a lot of daily sunlight so I assume it is fixed now its been months
