Conversation: The conversation between human and AI assistant.
[|Human|] I was in an accident some 7 weeks ago and all has healed fairly well except for a large swelling inside of my left leg, that does not want to go down. The area has a periodic (every few minutes) stinging pain, almost like a needle pricking. My doctor said it should have gone down in 3 to 4 weeks, but has only slightly. Any suggestions....this is playing on my mind and I am concerned about blood clot.
[|AI|]  Hello, Sprains or trauma may cause hematoma or swelling. It may take 3-4 weeks to subside. Use tablet choral forte twice a day for five days. Use cold and warm compression. Use tablet painkillers like NSAID to control pain. Elevate the foot end of the bed. If symptoms not improved please consult with your physician he will examine and treat you accordingly. Hope I have answered your query. Let me know if I can assist you further. Take care
