I wish I had some definite & sure answers for you. Dealing with & being diagnosed with CFS&/or Fibromyalgia can take some time & patience. Have you checked into Lyme disease? It has similar symptoms & people have been dx'd with Fibro & they have Lyme or visa versa.
Ok, first off-I think to begin with you need to find yourself a different Doctor. If your Doctor isn't listening to you & hearing you out about "all" your symptoms then move on. This is your life & I have a hard time with any kind of medical person who dx's you & then says you need what I have to sell. Kinda causes me to step back & wonder if the dx was real or did it just fit into the dx he wanted to give in the first place?
There are about 65 symptoms in Fibro & yours do seem to fit but Fibro is dx'd by eliminating everything else it could be. There are so many illnesses that have the same symptoms, so be patient, get the blood tests done & see what your new Doctor finds. One thing with Fibro is the 18 tenderpoints. Have you checked yourself for that? Google Fibromyalgia tenderpoints & you will find all kinds of sites that show where these are. They are spots on our bodies that are very tender when touched & they hurt like crazy if you push too hard. The criteria used to be, you need to have at least 11 of the 18 but I don't know if that still stands. I sometimes think there are more & I also think, if you have 9 or 10 should that mean you don't have Fibro? I don't think that should be the case.
While you are waiting for your dx, do alot of reading, learn all you can & be your own best advocate because finding a good Doctor, one who knows about CFS & Fibro can take time. I have a wonderful GP & I am so glad I found her. When you call for an appointment don't be scared & ask if this Doctor deals with Fibro &/or CFS patients. Don't waste your money going to someone who isn't going to listen to you. A Rheumytologist knows alot about Fibro, CFS, Lyme & Auto Immune diseases. If you can get a referral from you current Doctor that would be great.
Some of your fatigue could be some of your meds. I only take one med that can make me drowsy & that is a cyclobenzaprine. I take it at night to help me sleep because I have insomnia really bad, I use Melatonin with it & I can sleep very well, unless my Fibro is flaring.
We all are different & we all need different meds. It is all trial & error until you find what works for you. Some can only get relief with stronger meds. Fortunately, for now, I can get by with Ibuprofen 600 & Tylenol for breakthough pain. I hope it stays that way but I will just have to wait & see.
Well, I hope this helps some & answers some of your questions. Feel free to post again, I hope you can find some relief soon.
