Unexpected improvement - confused and worried

I’m so confused with the new Tadalafil tablets, the purpose of switching to these was that they
stay in your system longer then sidenafil. I was only expecting this to impact erection.
.
The improvement to urine flow was a surprise, and more recently I have some feeling back in glans head too. I still don’t feel anything when I pee, but I can feel some touch on glans now.

So that’s great, but it has me worried. When I google ‘tadalafil and urine issues’ it throws up prostate enlargement and prostate cancer, and these tablets are used to improve urine flow for people with those issues. And I am getting that benefit, which tbh has scared the shit out of me. I was only anticipating they were for erection issues.

I’m worried this sudden improvement indicates there is a problem with my prostate. Up until now over recent years we have been going on the assumption that erection, loss of feeling and urine flow were linked to a shingles rash a few years back.

Please someone offer me some advice or reassurance.
