You've heard of carpal tunnel and shin splints? (The muscle pulling away from the bone, or the casing getting inflamed). It can happen to ANY muscle/bone connection in the body... and what you're describing sounds like that. I'd be willing to lay money on the table that you ripped your connective tissue from the bone lifting weights, and then further aggravated it with continued lifting and activity.
Been there, done that. (That's how I blew out my knees. Small injury on top of small injury, and never taking the time to fully rest/heal/recuperate. Mine, though, had so many small injuries that I have a whole series of problems, including tears, cysts, fraying, etc. Damage one part, and the rest of them start to fall apart).
There are some serious treatments if you've permanently ripped the connective tissue away from the bone (from blood clot reattachments, to stitching, to shortening the tendons/ligaments, to partial or total joint replacement).
However, IF this is the case; the FIRST line of treatment is to STOP. STOP doing the activities that are making it worse, to let the injuries heal. Once they've healed up all they're gonna, then it's 3-6mo of physical therapy, and the reevaluating.
BUT... while this is the most *probable*/common thing to do, you could actually have done a number on yourself in SEVERAL ways; including not just CT damage, but also/or tearing cartilage (and the resulting pain is *either* from the torn cartilage itself OR from bakers cysts -which form near torn cartilage) in either your hip sockets or the cap of your femur or the cartilage in the front of your pelvis (with pain radiating out to each hip), or your coccyx/lower spine (ditto radiating pain)...tons of possible injuries here that I won't even bother to list, or nerve damage, or torn muscle (not tendons or ligaments), or arthritis, or, or, or.
Which all boils down to seeing your doctor. Because no one can diagnose online.
Go to you GP. From there, they may send you to 1 or more of a few different specialists (orthopedic surgeon, sports med, neurology, rheumatology, etc.). Hands down you'll need xrays (to look for stress fractures / fractures / arthritis / degeneration / partial dislocation / etc). If there's no glowing neon sign saying "Yikes!" in the xrays, it's MRI time to look at the soft tissue (tendons & ligaments), cartilage, muscles, & for any cysts.
