Hi Dr, I am a 45 year old male with a history of factor five laden. But have been off my warfarin for more than 3 years on doctor's advice. Haven't had any additional problems in the last few years, however, the last few days I have a sore lower inner thigh, running from under my groin to knee as a red sunburn or rash that is sore to touch (feels bruised). It has grown from a small patch to the knee in the last two days. The muscle also feels sore. I cycle and did so on Fri and Sat (the bruising feeling started Sat morning) I had originally thought the bruising pain was from my young son kicking my thigh with his shoes on but it seems to be getting worse. Other than that I feel no other symptoms. Can you give me some advice? Thanks
