Hey Miguel.I hate that you're still suffering.
You need to "dust yourself off",cause it's sounds like your Doctors have been beating you up,and find a Doctor that is caring and competent enough to get in the trenches with you and help you.
I know you want to know what's causing this and can it be healed?
In the short run I've sure you're looking for some relief.
What are you wanting from your Doctor,right now?
God Bless you,
Rick
eta: After years of living with pain,unless I'm at a 7 or above,I can look fine.
I was raised to keep my problems to myself.
It took me a long time to quit putting up a front at the Doctor,like everything is fine.When everything is not fine.
