I've been to a vascular surgeon to have PAD diseases investigated. It's quite common. They'll put an ankle cuff on your ankle and compare your blood pressure with that in your arm.
It turned out that a don't have PAD (I have nerve damage which causes similar symptoms), so I don't have experience of treatment, but I believe in some cases, they can put a stent in. Apart from that, you'll probably be advised to walk as much as possible until the pain gets too much.
The breathlessness probably has other causes and I hope you're having other tests to find the cause.
