Prescribed BP cuff. Cant get one anywhere...

So my BP went up from my appointment last week. (Last week it was 145/94, this week 168/82. Went to l&d last week and was monitored for 2 hours, had blood and urine taken, all was okay other than the elevated BP).

My OB wrote a prescription for a BP cuff. I went to my pharmacy, they dont do prescription BP cuffs. Called every pharmacy around me, and all medical supply stores. None of them cover prescription BP cuffs anymore...

Anyone else have this issue?
