Fibro is nasty and different for every single person.
I would definitely apply for disability. They are giving it for fibro more and more. I hope the doctor in August is helpful. Take care and know that there is a lot of support here for you and many of us understand because we have it.
As I said it is different for everyone --but I do believe that there are a lot of things that can minimize the symptoms - again different for anyone. Hang in there and see what works for you. II hope you can find the best doctor to help you find your path through this.
