The other day I was doing some speed deadlifts (about 60% of 1RM) and my form started getting sloppy towards the end of the workout - my lower back was rounding too much.
Anyway later on in the day my right hip just started to 'ache' like a bitch, and I've had the same pain for about a week. The 'ache' radiates down the front of my hip into my quad and I lose some strength in that leg.
It also starts to ache more when i've been sitting down for more than 45 minutes.
I'm thinking it may be due to a overly tight hip-flexor, although if that isn't the case I don't want to start stretching it and making the problem worse.
Does anyone have any ideas on what stretches/structural work I can do to alleviate this aching pain?
