For a couple weeks my left glute/hip area has been really sore. At first I couldn't tell if it's just muscular or something more. Last week I got a massage and she concentrated on that area and it felt much better.
Yesterday I was skating and my skate skidded on a stick in the road and the left glute/hip area felt like it "wrenched."
I am limping today
Did I pull a muscle? Should I put a cold pack on the area? Help please..
Can't tell you if you pulled a muscle or not, but IMO, you are concentrating the wrong area. You are right by saying it is muscular, but I believe the problem might be a tight IT band and is causing your piraformus to tighten causing the hip pain. Since the pain is in the posterior chain, the work (stretching, massage, etc) should start with lower lumbar and continue downward into the hamstring and IT.
Use a foam roller daily. By doing so, you will help eliminate the tightness, roll lowback to upper back for about 3 min, switch to IT bands, then glutes, then hamstrings. If you find a particularly painfull area or knot, stay in that area until about 75% of the pain is gone. Do this on a daily basis, and I promise you will eliminate your pain the future by 80%.
