So I just finished first week of school and I'm 4 weeks now.. I just feel as though my whole body is sore. My arms hurt at moving, to the point that when I move my left arm i just feel like crying and my leg muscles are very tight, I find walking difficult at times and stressing my legs in another way is just not option. Is this normal? Should I be worried? This is gonna be l long semester and I wanna complete it successfully.
