Hi @amoreenap and welcome to Mayo Clinic Connect. You will notice that I also added your post to the Heart and Blood Health Group so you can connect with members that have dealt with similar issues.
You can find the group here: https://connect.mayoclinic.org/group/heart-blood-vessel-conditions/

There is an article in the American Heart Association Journal that you might like to read : Orthostatic Hypertension - Critical Appraisal of an Overlooked Condition: https://www.ahajournals.org/doi/full/10.1161/HYPERTENSIONAHA.120.14340#d3e269

There is also a couple of discussions here on Connect that you might like to take a look at.
