I have had both my knees and hips replaced from 2010 to 2013, at some point I noticed swelling not going down and came to realize I had edema in both legs, but the right leg is about an inch larger than left. My right leg is also about an inch longer from an accident I was in , in 1981. My ortho Dr wanted me to see a vascular Dr., I did, he did ultra sound and said my lymph glands in my right groin area were swollen and wanted me to have a biopsy right away. Also I'm HIV positive so I get labs done about every 3 months and I talked to my HIV Dr first and she thought it strange because she had never seen a problem in labs. I've had so much done, this last April I tore my rotor- cuff and just got over surgery for that, so I'm waiting til after the holidays to get a biopsy. Wouldn't my labs show there was a problem?
