Sir/mam I am feeling a kind of numbness and weakness in right arm especially in forearm, shoulder region since last night. In early morning it was quite fine, but i went to gym and lifted some heavy weights as usual, now again a kind of weakness and numbness only in right arm, shoulder region. Usually i intake protein powder pre workout, intra workout and post workout of same brand (MB) which i used to intake earlier also then I didn't experienced any such, after gap from last one month i am going gym again, same powders i do consume. It's not any severe kind of pain, but slight kind of pain... Even last three days i didn't attend gym, but yesterday night slight pain was der when on bed, this morning I went to gym after three days gap, now started pain again. Like often i get pain in same arm, mild one and later it goes. Is this an issue related to protein powders i consume? related to heart? Nerves compression? Any blockage? I am scared, i am 30 yr, 178 cm height, 64 weight!! help me.
