I ended up going to the ER last night. The DR did an EKG it came back clean, said my oxygen levels are good. He doesn't believe I have Thoracic Outlet syndrome b/c I don't seem to have any problem with my arteries. He says the pain is most likely a pinched nerve, and all my other problems are because of my untreated thyroid. Also he thinks I might have sleep apnea which would explain why I can't sleep and keep waking up feeling shaky and weird. So I have some answers, thank goodness my hearts okay, but I still have to deal w the pass out feeling until I get back on my meds which won't be until January. Ugghhhhh..is there any way I can get some levothyroxine w/o labwork lol I know I can't just hopeful wishing....
