PAIN after root canal/extraction - help?

[Fixthepain]

6 weeks ago I was told I had a cracked tooth.  A root canal was performed.  The pain continued the tooth was extracted.  I have all sides of my neck tattooed as well as 100 other tattoos; I can tolerate pain - NOT THIS!  After root canal/extraction 6 weeks later it still hurts worse than anything.  The pain starts where the tooth was, causes ringing in my ear, head pain and severe jaw pain.  I have been told by the specialist clinically it ‘looks clean’.  He wants to cut it open again & explore around.  Please help what might it be, it hurts!  I’ve had 3 other teeth removed for similar reasons(mysterious) – my jaw hurts.  I read somewhere about painful mysterious tooth loss being a sign of some type of disease in the jaw?  I do not have a lot of money and have spent over $1,000(extractions/root canal/’flipper).  I’ve missed a lot of time at work, and have been medicated on pain meds too.  My teeth have been giving me issues for 2 years – any ideas are welcome I am almost 100% less this one location.

Intrabony pathology can generally be detected by conventional dental x-ray. If no pathology identified, reentry of socket is probably of no avail. Please be informed that dental pain is not always dental origin.Further investigation of pain source is warrented.
