I always have headaches, migrains, dizzy spells, back pain between my shoulders, just everywhere. I also have high blood pressure. I saw my dr and finally said I am sick and tired of being sick and tired. Do your job and find out what the hell is wrong with me!!! I had a sleep study done and have sleep apnea, a bunch of blood work from an arthritis specialist, I was very low in vitamin D so I tried that to no prevail. Well, The nuerologist did a series of pressure points and then I was diagnosed with Fibryomyagia. There is no test for it, they have to rule out everything else first. I have had MRI's, Cat scans, Sleep studies, blood work and so on. I suffer from chronic pain, always being tired, blood pressure issues, the dizzyness...ect I have suffered for years, I am 40yrs old, not over weight at all, I considered myself to be in good shape. I would tell your Dr to do his/her job or find a new one. It took me 10 yrs to get an answer, don't be a test subject. Get results. I am on Gabapentin for my pain, and on meds for my blood pressure after trying 4, and sleep with a C-PAP machine.
I feel so much better but I felt like you and it ended up to be Fibromyalgia. Good luck to you!
