welcome to the forum. It is a long road for some who deal with fibro to just get that diagnosis, but in the long run what matters the most is control of the symptoms. so here is your starting point by learning what you need to prove your well-being. You need to see a rheumatologist in order to get a diagnosis. Family doctors can make guesses but not really diagnosis this condition.
Have you seen an eye doctor concerning your vision problems? Whatever, problems you face some must be handled by certain body targeted doctors. Meaning like foot pain you see a foot doctor, bad headaches you see a neurologist. This way you manage the health problems you are facing and have a clearer picture as to what is wrong and how to cope.
On this forum members can tell you about the symptoms they face and how they cope with each problem. The forum is loaded with smart hints and coping skills. But each member here knows the importance of having a good team of doctors who can provide good care. Please let us know more about your health problems so we can offer more coping skills.
