What Does An "MS HUG" Feel Like? I Have Been Having Severe Pain Around My Rib Cage Directly Under My Right Arm Pit And Sweeping Around To Just Below My Breast. At Times It Is A Stabbing Pain; Other Times It Feels Like A Muscle Spasm, But Always Feels Sore To The Touch.
You just need to go to your doctor and have him/her to check you out..that can be many of things,and we just don't know what it could be..and have you put a cold pack on it to help with the pain?try that see what it does..
I just wouldn't use lemon juice,because you never know what will happen. You need to call your doctor and ask him the question's,because you may get the answer yes and it hurts your liver...your liver is very sensitive..
