I have not been officially diagnosed with POTS yet, but I am scheduled to go see Dr. Goodman at the Mayo Clinic in Scottsdale, AZ middle of next month. I wanted to know if anyone has been diagnosed with fibromyalgia along with POTS? I have been to several doctors and they acknowledge that I have some weird symptoms such as the tachycardia that aren't common to fibromyalgia, but other symptoms such as the horrible pain in the back of my head and neck are more common in fibromyalgia patients. I am curious if anyone has symptoms similar to these along with palpitations and the difficulty in swallowing and sometimes weakness in my arms and legs? Also, I notice that whenever I put my head down and then bring it up again, I get lightheaded and need to sit down. Additionally, if I take a hot shower,I start feeling dizzy, have palpitations, and get confused right away. I am just wondering if anyone else has any of these symptoms because sometimes I feel like I'm the only one experiencing them. Nicole
