<s>[INST] I had a minor injury to my spinous process at T12. A loose toilet lid fell onto it while sitting on the toilet. I am skinny and the spinal bones are very prominent, so it hurts, has a red mark and is swollen. Should I worry about this? I put ice on it already, still hurts a bit. [/INST] Hi Dear, Welcome to Chat Doctor. Understanding your concern. As per your query you have concerned about swelling in the backbone. Well there can be many reasons for symptoms you mention in query like hematoma, fracture, infection after fracture and inflammation of disc. I would suggest you to consult orthopedic surgeon for proper examination. Doctor may order x-ray, CT scan or MRI to confirm the diagnosis. Doctor may prescribe antibiotics along with anti-inflammatory and anti coagulant for hematoma. Doctor may also recommend surgery or may Chat Doctor.  For now take ibuprofen or acetaminophen for pain, take proper rest and apply warm compresses. Hope your concern has been resolved. Get Well Soon. Best Wishes, </s>
