my husband has had a swollen like cyst on his back near back bone, it has gooten verylarge, seems t be fluid flled. Has had it for a year or so, and it has gotten bigger. Now his right ankle stays swollen along with that same side he has trouble with his hip. There has been a sore like on the back of his leg close to his ankle. It itches alot. Could one be causing the other? It s getting to where he can t walk far before he is out of breath and hip hurts so bad. He has knee problems too because he is a mechanic and works alot with knees bent and on concrete.
