My father feels pain in his heel area. He often says that it hurts like a prickling thorn. His lower legs are little swollen and when long press with thumb in ankle region leads to a depth like impression for 1-3 secs. And then it again becomes normal. When he sits for longer period of time. He does not get any power to stand until he take support from anything. He often says that his uric acid has risen which is causing this problem. Therefore I need to know for what reason this is happening. And what is the remedy for this?
