About 3 weeks ago I strained both quads trying to perform sprints and not warmed up enough. The strain stopped me in my tracks and prevented certain activities. However I am a fitness instructor.. so I continued to work but avoided movements that caused me pain.. now since then I noticed a dent in thigh. Only in my right one;which was the worse of the two when strained. I m wondering how long until this goes away and should I be concerned?? I ve resumed physical activity. No serious pain,but that area still feels scarred ..(thats the only word I can think of) thoughts???
