<s>[INST] I am having pain on my right side from below the ribs till the umbilicus. I had undergone gall bladder removal surgery and suffered from ulcer few years ago. Yesterday my friend hit on my stomach ans since then it hurts badly. I did not have any vomiting or other problem just pain the abdominal area. Please help me. [/INST] Hi, it might be nothing but get it checked by a Doctor if you have severe pain. Do you have any giddiness or fainting feeling? Any swelling or fullness of the abdomen? If yes, then you should definitely get an Ultrasound done to rule out any injury. It would be safer to get it evaluated. If you think the pain is subsiding, and you do not have any of the above problems then you might want to watch for another day before seeing the Doctor. Take care and do let us know if we can be of any more help, Take care, Chat Doctor.  </s>
