Over the past week I have been experiencing stabbing/shocking pains throughout my fingers which has started to spread up my arm and my whole right arm goes numb. Today I am feeling the same feeling up my right leg from my feet all the way up to my thigh. I'm 21 years old male weighing 8 stone 6. Am I getting these problems because of my weight? Also when I go to pick things up with my right hand it seems to be a struggle and also cannot make a full fist.
