Are you in therapy for your chronic pain? Chronic pain causes many mental health issues for us...and having someone to help you sort through things, and yes, reduce your pain in alternative ways, is a must have imo!

SOMETHING is causing all this, and it might not be just one thing.

Have you seen an allergist by any chance? Having allergies or even one allergy to something can make you feel crazy, not only give medical illness. I will share that I was so brittle with allergies that the doctor saw no one else the day I went in... he also had a lady whose allergic reactions all ended up as a heart attack! Two girls were deaf from allergies and once he got them squared away, they are hearing and normal. If you can't see an allergist, then try keeping track for 2 weeks everything you eat and come into contact with (oh I know this is hard work, I've done it many times)... and what you felt when too... you may find that your joint paint (for instance, example only) comes on at night after you eat white foods (potato, bread etc)... or your muscle spasms are worse if you don't have enough water...

the body is very complex and most doctors don't have the time to help us sort things through... but to have a therapist help you know you aren't crazy and who can help you find some ways to reduce your realization of pain, well that's a good doctor!
