I just had like a 2 month break from workout, and I just came back.
Mind you, I have never experienced this before.
This annoying problem happened after my first sets of benchpress with dumbbells, my left side/arm seemed to go weaker than my right, the left arm could barely get it up whilst the right arm could much easier (This also happened on all the other exercises using triceps, pecs and shoulders). Towards the end of the workout my left shoulder started to hurt alot when I moved it, especially over shoulder height or at shoulder height. And today while doing biceps curls my left arm was significantly weaker than my right (I was doing 12 reps and at the last set I only got to about 6 reps with my left arm, but my right could easily keep going to 12). And i could see my left arm veins got huge and the right arm was more casual (Not as much pump yaknow?), haha, I think the veins could be because my left arm was fatigued, or maybe something causing bad blodflow into my left arm or maybe for the worst a inflammation?
Also, the whole left upper side of my body is hurting like a bitch, my right side is fine though.
Anyone know what this could be?
What should I do? Take a break? I just began working out again! :(
