Hi, I m 21, I m 5 2 , I weigh 135 lbs, and am physically healthy for the most part. Tonight, I noticed my lower back felt bruised and it hurt to simply adjust myself when sitting. Then, went to bed, I decided to lay on my stomach to avoid the pain, but my stomach also felt bruised and felt a hard rod-like thing at the top of my abdomen. When I touched it, it also hurt. The pain feels familiar to when one does exercise, but I haven t done anything strenuous, or done any abdominal exercises that might cause this pain. I m a little scared because I ve been taking a Chinese almond for weight-loss and I don t know if this might have anything to do with the pain, but even then, I ve only taken it for a few nights and I hadn t taken one in two nights until today. I hope this is clear and hopefully I can get some answers...
