Back Problems

[A.Jay]

hey guys i gotta problem with my back the muscle just above my right shoulder blade is very tense should i rest or will it be fine to carry on training (im 15 i don't know if that makes any difference but im still growing) and also i've been getting this feeling like a stich in the side of my stomach when im not even doing any exercise

its pissing me off because my body feels like it needs to rest but ive just started half term so i want to train hard this week and i know i'm not in fighter condition yet so it feels like i can't be missing out on training

listen im sorry for startin a new thread on this but anygot any advice on this. i also have noticebly more muscle on my left arm than right and was wondering if training on this could make it worse (ive been told that it will just even itself out if i do as much with both arms)
