Dr. Adam Favro - Chiropractor in Saratoga Springs, NY
Seriously, call someone like this. I'm going to bet it costs less than $100 to see the guy for your initial visit and you can get started with fixing your hip. I have bad hips at times. I have a bad back at times. I have had back pain so bad that NSAIDS and shit like tramadol etc. could not ease it. I have laid on the floor at work in tears. I have pumped ibuprofin in my system on long runs to kill the hip pain.
It will get worse if you ignore and it will cause worse problems and deadlifting won't be an option. Our bodies are a system and you can't train around a problem for long. You probably do not need a $2500 MRI. You probably don't need surgery. You probably need someone to go in and massage the hell out of your hip flexors and break up the lesions, get everything back in alignment and then get on a stretching and strength program to manage the issue.
I know that chiro is not a magic bullet but sometimes these guys just know their way around muscles and bones better than internet strangers or doctors. They don't charge a heck of a lot of money either.
