<s>[INST] My husband is 56 has two stents angina. Experiencing pain in one area on right lower back close to the side. He is diabetic. Also has had protein i urine for past several months. Any suggestions? He is having chilling tonight. Pain has been going on for almost 24 hours [/INST] HIWell come to HCMI really appreciate your concern, if there is history of angioplasty then first thing you need to do is get done the EKG test this would rule out the possibility cardiac disease, if this turned negative then condition nothing to worry and this could be muscular pain, hope this information helps, take care. </s>
