I know you said you tried something for anxiety but don't give up. I believe that's your issue. It's one that many doctors will miss. There are many things you can take but my Mother takes a very small dose of Elavil at night and it controls her symptoms. There are others but they take time to work, as does the Elavil. If some of the new meds made you worse, Elavil just might help, as it is one of the older ones. She was diagnosed with inner ear and anything else you can think of. It took almost 2 years of almost non functioning before she saw a neurologist who recognized her problem and treated it. She has been great every since! It is a crazy display of anxiety but believe me, I saw it in her and it is very atypical, for sure!
I don't feel like I have anxiety, I'm never nervous or have heart palpitations, I have low pressure usually 95/68 but that is normal for me When the doctor gave me medicine within hours it amplified my symptoms and I made me even more lightheaded. At this point I'm willing to try anything, I wake up everyday lightheaded all day long, but when I yell, laugh, cough, sneeze, and or drink any alcohol.. anything that builds pressure it makes it worse.. I was even thinking about going to a chiropractor for an adjustment to see if that will help, kinds lost for what to do next..
