Heart rate went from 80bpm-130bpm when i stood up within 30 seconds and bp went from 126/80 to 131/95. i get dizzy and weak when standing sometimes, this comes in episodes that last for days with other symptoms before improving. could i have pots?

Could have but the DX amcan only be made by proper testing including tilt test. Other things tat might do this include being dehydrate or hot or taking supplements wise side effects include postural tachycardia, discuss with your dr.

Yes you do have POTS If this is long standing you may have EDS or another hyper mobility syndrome If this is a recent problem then see a cardiologist , make sure you are not dehydrated and that you do not have deep venous thombosis
