Friends, when I squeeze my right biceps, I get tingling and cramping and this is the case for an average of 1 month. Moreover, November is pretty rested. If I am tired, I will say ok, but I am not tired. I wonder if I have a magnesium deficiency. Then my strength is in the right place. I can give maximum strength, but when I squeeze my biceps empty, a cramp there is pain like tingling. I would appreciate it if you could inform me about it.
