I was wondering how many others have high blood pressure and dive. Are you on any specific meds for it? I was told at one point some medications are not compatible with diving. I'm made to wonder if this was the doc trying to sell a new drug or if he was telling the truth. I was told I HAD to take Diovan. I am currently on Lisinopril as its cheaper than the other medication. I switched to it after last diving season.
