All I can think of is maybe get an iv. If you’re sensitive to weather and allergies then stay inside and maybe take some allergy meds. Sorry I can’t help more. I hop you get to feeling better.

40s suck. Mine would skyrocket (usually around 170, but max was a tad over 200bpm). Then often crash after sitting down. If the bottom stayed up at 60s or 70s, it wasnt so bad. But 40s, just knocked the wind out of me. Spironolactone and metoprolol really really helped. The swings still happened but not as severe. It stopped the symptom escalation and ER visits (my potassium would drop out, not huge but cardiologist says he has encountered others who are very sensitive to moderately low (3.0) potassium. After 3 years on those, i my heart rate is not always the result/target of standing. Now digestive, better and not. At least i have more functional living. Oh, i also added sodium in the morning, like many other. Then lije 40 ounces total in first couple hours and seems to help a lot. Also strongly reclmmend yoga type stuff. My physical therapist teied andbit really helpedcthe pots. So now a believer because it was proven to me. Simply try holding your breath while changing positions and the pursed lip breathing while standing. Easy to try and you'll get some immediate answers if it works for you.

Reading your post again. Eye movement desensitization and reprocessing (emdr). Google it. maybe find a therapist who practices it. With both the POTS and the the dizzy and ear, it could help a lot. I originally went to treat increase in migraines (1 a day to 3 a day), but helpful in all areas of my health. I didnt believe in this type of thing before, but it worked.
