Injury 8/10 - 11/10 and still healing

I think I tore my right quads slightly at the Pump FX class.  At first I thought my quads were just aching so badly because I hadn't done squats before, but then I realised that there was a sharp pain near the top of my right thigh so I pulled back on the exercise and didn't go to uni on the 8th.  It's mostly better now, but I can still feel it, especially if I lie on my front.
