my right upper arm is aching SO bad , i feel like holing myself in bed right now till morning , though its only 10pm. I've to keep it at a bent position and if my arm is straightened the ache is kinda like what u would feel on yr thighs if u walked non stop for 1 week without resting. And i have not even done any strenuous stuff ! aargh. will update tomorrow when the ache goes away. ciao.
