Hi, I've been experiencing pain and discomfort in my upper right thigh joint for about two weeks. I originally thought it is a muscle strain because I'd begun running on the treadmill, so last I did exercise at all to rest the muscle; however it hasn't subsided. Last week I began taking 600mg Ibuprofen but it didn't stop it completely. It more painful when I sit for ling periods and especially when I'm asleep, it wakes me up. The pain is sort of dull but it throbs every now and then. On the pain scale it's maybe a 1 or 2, not unbearable but I notice it.
