<s>[INST] I have a buzzing in my left upper groin area. Feels like blood rushing through a vein or a cell phone buzz. Lasts for 2 seconds and happens about every 15 minutes, all day. I looked at my inner thigh this morning and I can see a prominent vein running to the area. The identical vein on the other leg is recessed and not easily visible. Just started a month ago and is getting progressively more often. Any ideas? [/INST] Hello,Based on your description of complaints. What I can infer is that you may be having a left groin strain. Although you have not mentioned you age and other details what I can tell you is that it commonly occurs after a strenuous activity. The vein that is prominently seen may be due to inflammation. I would suggest you to wait for a few more days and consult your physician who can advise you on the appropriate management after clinical examination. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Santosh S Jeevannavar, Orthopedic Surgeon </s>
