With a psa that low you should be singing in the rain.
I had my op 16th Dec 2016 and in April 2017 I bought 30 pads as it seemed a good saving and I still needed them. Then it suddenly got a lot better and in early May I noted I hardly needed to wear them except for stress leakage. I ended up giving about 20 pads, they're in 10s in a Boots 30 pack, to a charity shop.
Although there were residual problems. One was leaking when I'd just been, fasten up and feel a dribble. I didn't know it was fairly common but the hospital sent round a questionnaire and that was one of the things it asked. Until then I thought it was just me. That seemed to clear up after about 2 1/2 years.
The other is a small leak when first aroused. That still happens. Although I've still got about 40% ED.
Stress leakage can still happen if I get home wanting to go to the loo and bend down to take off my shoes for example. It's very rare.
