Having Nerve Pain in both hands, chest, neck,face,head and back and going down to groin region. Muscle Pain sometimes also. It's mostly seen with down neck position for long time(i.e. when using mobile). And when stretching neck and upper body. I got lightheaded & shortness of breath sometimes while walking for long time. Sometimes having balance problem and tremors also. My age is 21 only. This is happening since 5 months. History- in december 2020,one night, I suddenly lifted a very heavy bag of books & got blackout for 5-6 seconds & got panicky(that day I was hungry since morning). After that, I was doing well for 2 months. Since then gradually this problem has started.
