Tearing sensation in hip area?

Jxnsmma

So, I had something really weird happen yesterday... I was putting my sons quad away, pulling it into the shop with my right hand/arm when all of a sudden i felt this weird tearing sensation in my left side hip area, basically just behind my hip bone. Hurt like a bugger and lucky me I had TRX bootcamp 20 minutes later. I went to the class but it hurt. Iced it when i got home and took aleve. It hurts this morning like a pulled muscle kind of hurt. Feels soft tissue, not skeletal. Hurts most when I use that leg to climb stairs when it is the up leg and I put pressure on it. Feels better if I put compression on it and use it. Hurts to press on it with my fingers tho. I noticed the last couple days before this happened the area kind of felt tight, like it was worked out, on both sides. I assumed it was sore from bootcamp...

Anyone ever had this happen before?
