<s>[INST] Lower leg above ankle VERY swollen with bubbles that Can drain clear liquid. Rest of leg swells too. Seems to be a hard bump mid shin and from there down leg swells hard and round. Right leg. Left has no bump but is starting swelling and bubbles. Kidneys? Skin also pretty dry. [/INST] Hello! I have been through your question.Related your concern i think this could be bullous erysipelas caused by streptococcus beta hemolytic.Usually this is common in diabetic patient( because of the fungi in foot that cause sores), immunocompromised patient and in patient with lymphatic obstruction.I suggest to do e physical examination by an infectious diseases specialist, to do  culture of drain liquids in order to find the proper bacteria and to start as soon as possible Intravenous antibiotic( usually I prescribe ampicillin or cefazolin) for better result.I hope my answer helps you.I wish you a quick recovery. </s>
