Leg pain and stiffness

About three months ago I had a very sore area on my left leg about 6 inches above my ankle. It was very painful to the touch first. Then later it hurt whether you touched it or not. It was very tight and about 7 inches in diameter. I was told to take Ibuprophen, put heat on it. Then about a month later it was the same and the same thing occured on the other leg. I then was givenfluid pills. That seemed to help however, I then started having problems with pain and stiffness in my legs. I was told I could take aleve for that. Well the 1st issue is getting better. However, the stiffness in my legs is an issue. I can stand up at my desk at work or at night and have to hold something to get myself together. As I walk more it feels a little better but still sometimes painful.

Thanks
