I am being refered to a surgeon due to a large popliteal cyst. Hyperintensity within posterior horn of medial meniscus due to mucoid degeneration. It does not extend to the surface of meniscus and is, therefore not a tear. I have been having major problems with being cold. I mean actually, not being able to get warm, unless I am under a lot of blankets. Could these two problems be related??? Thank You. Lyn
