i've been experiencing pain on my upper right arm that is getting worse and worse on a daily basis. i haven't been doing any kind of lifting or hit it on anything, so i'm not really sure what it could be. also, i'm usually in constant (not overwhelming) pain in my lower back and on the right side of my body. lastly, i would say on a weekly basis (sometimes more), my chest seems to flutter for a period of a few seconds and i'm not sure why. when it starts, you can actually put your hand in the area of my heart and feel my chest. i'm not really understanding why i'm in pain and why my chest/heart is doing that.
