As EGDM said, welcome to the club.
First thing that I recommend that you do is stop training. BJJ is not good for the hips.
I originally tore my labrum, and rolled on it for 3 years, making it worse and worse. Obviously, I did not know that I had a torn labrum until about 3 years later, as the pain was not that bad. It just felt like a pulled muscle that limited my mobility. If you stop now, and stop the damage before it gets worse, you might be able to continue BJJ in the future with out needing a hip replacement in the next 2, 5, or 15 years (it depends on the damage that you do now).
I had 20% of my cartilage removed, they repaired my cartilage in 2 places, performed microfracture to promote more cartilage growth in the removed sections, and they shaved down the bone in 2 places in order to prevent further tearing.
The recovery is much longer than that of a hip replacement, as the the surgery/area is delicate and needs a long time to recover. I could swim after about 6 months, and slowly tried to return to bjj at about one year. I am never supposed to run or jump again (as that will make me need a hip replacement sooner). It was/is an up and down process. I take a lot of natural supplements to help (they maybe placebos, but at this point, who gives a shit, I just want to role!) such as fish oil, glucosimine chondroitin, and tumeric on a daily basis. I tried to return to rolling 2 days a week, but could not do it. Now I role once a week, and have accepted that as my reality. I have fun, stay in ok shape, and tap to people I used to kill.
My best advice for you would be to be PATIENT!!!
Do not return to drilling or rolling until you are really ready.
If you have surgery, rehab well and take your time....it maybe up until 12-18 months. Not being able to run or jump....it really sucks.
If I had known I was fucking up my hip to anything near the level that I did, I would have stopped and gotten the surgery a lot earlier than I did, and potentially would be much more mobile than I am today. I was a 35 year old purple belt when I had the surgery.
I recommend that you check out the post below. I have also p'mailed a lot of these guys in the post below. Once again, be patient and and listen to your surgeon.
I guess that I should also mention that I have had my knees scoped 3 times. That was nothing compared to the hip. My knees feel fine. The hip is a much more complicated joint, henceforth the long recovery time.
Good Luck!!
