I think I have fibromyliga and my doctor doesn't believe that there is such a thing. Should I go to another doctor to see what he thinks. I have researched it on like and I have a lot of the symptoms, but when I go in and mention to my Gp I just get a smile and shaking of his head and says take some Tylenol and you will be fine.
Your doctor does not believe in such a thing as Fibro? You need a new doctor. Find one, immediately.
Word of advice: Do not mention that you have been researching it online. When you go to a new doctor, do not mention ANY of the research you have done. There are many people who do suffer from hypochondriac disorders. Many hypochondriacs will self-diagnose. The minute you tell the doctor that you have been researching this and you think you have it, they will assume that it is all in your head. Many doctors have a "god complex" -- that ONLY they are qualified to say if you are sick or healthy. Most doctors really do not like it when a patient is aware of the things going on their body. And they really hate it if the problem is past their area of expertise.
So, get a new doctor. Tell that doctor what your symptoms are in the greatest detail as possible. You may even want to start keeping a diary of when the issues you have flare up. Or, the next approach would be to visit the ER if you encounter a flare up that is really quite bad. But do not tell the doctor about your research. The doctor may just think you are wanting attention or worse.
