For the last few weeks I've been having problems with my lower back. I have been stretching before and after each workout. Good support for my chair at work. Using ice and heating pad to help with the pain. This afternoon after I got done with my workout I noticed the front part of my upper thigh going around to my hip gave me a large amount of pain. Each time I took a step the pain increased and I was reduced to a shuffle.

This seemed to be a gradual increase of pain but it would stop for a day or two but came back. After today's work out, I noticed increased pain as I got off the bike. I had a lot of pain getting up off the coach and had to shuffle along in the house. I tried a warm bath with Epsom salts. Then I used ice packs, it doesn't feel any better.

Most of my past injuries were obvious and I knew I had an injury. This is the first time something felt like a mild problem and now turns out to be a really painful injury.
It deals with the muscles : Sartorium and the rectus femoris.

I'll take it easy for a few days and apply ice and heat. Then see what happens. Still trying to figure out how it happened.
