Be careful how many different meds your daughter goes on as I have the same thing as her. Multiple concussions do to car accident as well as a fall I had. I suffer from headaches I've had now for 23yrs. I was diagnosed with POTS in 06 at the cleveland clinic. My POTS is do in part from the accident in 87 as well as pain doctors prescribing to many preventive meds and abortives for the headaches. The meds were toxic to my nervous system. Almost any drug I take my body over reacts to the drug and it gives me really bad side effects and they make the POTS worse. I basically only take a pill for my BP and 1 for my HRate. I also take elavil for sleep and Vicodin for the headache. So far those drugs have helped and don't affect my POTS negatively. If you want to talk you can always email me I have a lot of self awareness with both these conditions your daughter and I have. It's a lot of trial and error.
