I am currently trying to figure out why my left quad has lost tone, strength and mass. It is quite floppy as compared to my right and is approximately 1" smaller in diameter. I experienced significant pain in my left knee/leg some weeks ago and received some Prednizol (?). The pain is gone but so is the quad (somewhat). I can walk (with a slight limp) and bike and I plan to ski next month. I have not consulted an MD yet but I do have a physical next week. I can't put my finger on what may have happened other than something that might have occurred on a long bike ride or some kind of back related issue from sitting in front of a pc for hours.
I'll be 65 next month and I'm concerned about whether there is an issue with knee or back that might be causing this. I just found this forum and have been impressed with the responses I've read.
Would anyone care to make a guess or offer some advice? Thanks.
