<s>[INST] Hi, i have sharp pain around my front, right, lower rib area (like intense bruising) i have been told that i may have ruptured the lung membrane or  may have gallstones.. i forgot to tell the doc that my coccyx feels bruised too - can this all be related? [/INST] Hi and welcome in Chat Doctor. I can understand your concern. You mean rupture of pleural membrane which in medical words is a Pneumothorax. To confirm it a chest X-Ray is needed. In cases in which chest X-Ray does not conclude, but the clinical suspicion is high a thorax CT is indicated further. For gall stones an abdominal ultrasound should be done to see them. The coxes bruising i don't think to be so related with the pleural rupture. Keep consulting with your doctor for the choice of treatment. Best regards Chat Doctor.  </s>
