Anterior thigh pain

[Emanuele]

I would tend to exclude any kind of nerve problem. An affection of the Femoral nerve would give you a distributed paresthesia (pins and needles/numbness) on the anterior aspect of your thigh, and inner aspect of it down to the inner aspect of the leg till the ball of the foot via the saphenous nerve, and you haven't complained of any of these problems plus an objectifiable muscle weakness of your quadriceps, so don't worry about trapped nerves! Honestly I can't imagine how doing those stretching you reported, if gently performed and well executed, may give you any trouble/issue. Chances are that you may have overused some of your muscles of the anterior compartment of the thigh such as rectus femoris or maybe sartorius for example, during that section. Just give it another 4-7 days to see whether this disconfort you have at the moment will pass by, and try to avoid any strenuos activities in this period of time. See what happens, it doesn't sound very concerning to me, but still it is not very easy to have a clear idea if we cannot test you from real. Of course if after a period of 10-14 days from the onset of the problem, your presentation will still be the same or, even worse, it will aggravate (hopefully not!), then you may take in consideration to have a proper and full examination carried out by a colleague.

All the best
