A pain clinic is only going to mask the pain. You need to find an answer. Do you need a referral to get to go to a specialist. Call your insurance company. With mine, I can go to any dr and dont need a referral. If you do need one, keep going to your PCP and telling them your in pain...something is wrong...they have to do something for you. Just keep pushing. You know your body and if your in pain then you need someone to do something about it.
