I have had two baker's cyst for over a year now - one in each knee - variable in sizes, and at times very painful. A surgeon confirmed that the knees had no damage and that ligaments were fine, other than AS there does not seem to be any possible explanation for the problem. When one ruptured and I could barely walk for a few days - and after a few weeks the cyst built up again. As seen on Youtube videos some are fighting the cyst with cold patches and compression. I have experimented with knee stockings - but with mixed results so far. Anyone here having a similar problem ? Thanks.
