If your doctor still thinks everything is okay, then try support socks/stockings. I've been on BP meds, including olmesartan/hydrochlorothiazide, and I still need to wear support socks. I have a pair for light support and a pair for moderate support for days when I'll be on my feet a lot. This also helps my ankle pain.
Just a thought.
1. You MUST take your meds every day. Period. No lapses.
2. Ask your NP why you are not on diuretics ("water pills").
3. Ask your NP about using a generic med called olmesartan--brand name Benicar. It works very well, minimal side effects.
4. prepared foods of all types are high in sodium, so stay away from them--sausage, salami, ham, etc. The deli counter is an especially rich source of sodium.
Diuretics? I have been on Benicar (olmesartan) for many years, works very nicely. Amlodipinealso said to work nicely but may diminish your taste reception.
