I have a severe pain in my leg between my ankle and knee,not my calf.It has been hurting for 2 days,and is not stopping,and I can not sleep and Pain medicine (tramadol) or Aleve,or acetaminophen 650 meg (2 of them) at a time are not helping.The pain is inside the leg,and I think it might be swelling.The pain starts out light and then gets very strong,like a sharp stabbing.What could be wrong???? YYYY@YYYY . Thanks Judy
