<s>[INST] I have pain in my left knee. I woke up this morning unable to walk on it for several hours. It is still sore and I have trouble bending my knee. When I went to bed last night, I was having pain in my hip all the way down to my ankle. I took some pain medication and went to sleep. I have had an abdominal blood clot repaired in the past and this is worrying me. What do you think? [/INST] Hi Dear,Welcome to HCM.Understanding your concern. As per your query you have  pain and soreness in the knee. Well there can be many reasons for symptoms you mention in query like damaged Menisci , tendinitis , osteoarthritis , gout , bursitis or chondromalacia . I would suggest you to consult orthopedic surgeon for proper examination . Doctor may order certain tests like CT scan , MRI and physical examination . Doctor may prescribe muscle relaxant along with anti inflammatory and recommend physical therapy . Doctor may also recommend surgery in severe damage. For now apply warm compresses , take proper rest and take ibuprofen or acetaminophen for pain . Hope your concern has been resolved.Get Well Soon.Best Wishes,Dr. Harry Maheshwari </s>
