See a physio (if you have not already).
What I thought was a quad strain was a quad tear that ended up taking 9months to completely heal.
Did it yesturday, hard to describe how I actually injured myself it was on the descent performing a squat. Struggled to walk yesturday but haven't had any sign of pain. I'm away on work miles from any physio. I don't have a taxing job.
I won't be doing anything to cause further damage until I've got it checked I was just seeking advice as I haven't had an injury before.
