<s>[INST] Lower middle abdonmen pain, initially I thought it was just soreness from doing these new sit-ups but no one else who I was working out with experienced anything similar to this. I m a dancer and whenever I had to do something that involved strength in my abdonmen I d feel a sharp pain there. Thinking that it was only a sore muscle, I continued to do the counts and what not. That made it worst! Now it hurts to cough , walk, sneeze or really do anything. Is this something to be concerned about? Any ideas on what the cause of this may be? [/INST] Your description is highly suggestive of muscle injury - a few fibers might have given way? When there is pain, rest the part / give cold compress / take Over-The-Counter pain reliever with or without muscle relaxant - for a day or two. If there is any doubt, you must see a doctor. If there is no improvement / if there is fever, vomiting, bladder or bowel symptoms - you must go to the doctor immediately Good puckish you speedy recovery </s>
