I am a 31 year old male. From past couple of days, I do see a throbbing / pulsing in my left thigh. It is around 6 inch above the knee in the inner thigh. I am not having any pain however, this has been irritating me as it happens very frequently and randomly. I had my blood and urine works done recently and apart from borderline bilirubin levels, everything is normal. I don't drink and didn't have many liver issues, so not sure about the 1.3 bilirubin levels. Let me know what could be the reason for this and how to proceed. Any response would be greatly appreciated. Thank you.
