Welcome I am very glad to meet you. I am new here as well, so far everyone seems very nice. I hope you stay and get to know some of the other people.
I am very sorry to hear you have chronic pain and dont know cause yet. It sounds like you ve been all over and very proactive in trying to find a solution. It must be very frustraiting and exhausting Im afraid I dont know much about differant types of illnesses associated with chronic pain.... BUT... the other folks here will probably have good ideas. Anycase, just want to say Hello
