<s>[INST] I am experiencing pain in my lower back left side going down to my goin area. My feet and legs are red and very swollen. I have had tests run but no diagnosis to date from a physician. I am a smoker,and drink an excess of beer. I thought I had a Hernia but the doctors say no. No one has prescribed any medication other than local pain medicine. I do not take any other Medications. Do you have any suggestions as to how my goin pain is related to the swelling of my feet and ankles ? [/INST] I think u may have cellulitis which can cause swelling of limbscheck for renal function testdo an ultrasound abdomen and pelvishaemoglobin can be checkif everything normal do Doppler for diagnosing deep vein thrombosis </s>
