I recently had a follow up visit with physician regarding a recent mri of my knees. determination was absolutely that I have arthritis behind knee caps but most painfully I have torn meniscus in both knees. h Handling it with surgery. Question is that doctor mentioned hazy opaque or cloudy areas that could be indicative of some possibly blood disorder I believe but he felt it was rarely the case as they see it often. I could have blood work done to discern yes or no and put my mind at ease. I am not concerned except that I cannot recall what it was called. Believe it started with m . Could you help me recall what it was? I believe I will recognize if I see/hear it.
