Could this be related to commuting too much?
I commute 150 miles per week on the bike and rarely get any leg pain while cycling. I've been commuting for years, I'm not a youngster, and I stretch almost every day.
If I hike on the weekend, particularly on Sunday after a day of rest, I can get pain in the quads while hiking downhill or down stairs, the pain can be acute. When it happens, the quads hurt as the knee is bent. MD's, PT's, sports MD's have not figured it out yet.
Am I cycling too much?
Anyone have this problem before?
I'm not asking for a diagnosis, just more data points.
