Yes Rach I am familiar with this. This is when I first figured out that some of the symptoms I was having was from perhaps Autonomic Dysfunction. I have neuropathy and wonder if that is part of that.

My internist gave me a big print out of info on POTS after my daughter had brought up with my ENDO how fast I bounce back when in ER and get IV fluids. She said I think you may have POTS. The info talked about Dr Low at Mayo who did the research on mestinon for POTS.

In response to this she told me to increase my salt intake a fair amount and drink a gallon of water a day. Now the water I was already doing but not salt. I have problems with regular salt. I finally found a salt online I can use without problems Pure Ocean.

I am wondering if it is autonomic dysfunction that that is why sometimes when the salt and the water and the mestinon arent hitting my body just right I get low bp rather than higher. Tesday at the docs my bp was 132/70 which my daughter pointed out was the highest she ever had seen. Yet today I am having the ache in my chest again. I am sure it has to do with having to push higher amounts of mestinon in me starting during the nite as my breathing got alot worse Tuesday due to the doctor trip. I will talk abou tthat elsewhere.
