[|Human|] I have a bruise on my right side. Have not hit it or been hit by anything. 2 days later, I am having lower back pain. I am going to the bathroom normal, and have not seen blood in anything. What could cause this. This is the 2nd time this happened in the last year
[|AI|]  Hi I did review your concern and question. Your lower back pain can be due to multiple reasons. I would advise you to consult a rheumatologist for complete evaluation including-xray, cbc, esr, crp-MRI spine,HLAb27 if required afterwardsFinding the right cause is important to start right treatment in back pain About the bruise you need to be investigated for CBC, platelet count and coagulation profile. Also, both back pain and bruise can be related with respect to an autoimmune phenomenon. I hope this helped me know if any more questions or concernsWish you best luck ahead
