(Concern) Acute urethritis and cystitis

I am a housewife in my 50s.

Due to fatigue, intense exercise, sauna, etc.

Acute urethritis occurs frequently due to inflammation.

Pain accompanied by blood mixed with urine after urination

It's so severe that I can't do anything.

Go to the hospital each time to have a urine test.

I received an injection and was prescribed medication.

However, as I get older, gradually

When the frequency increases and antibiotics are taken

I'm not sure if it's a side effect, but the skin is soft.

A rash has appeared on the area and it is itchy.

That area is turning black.

Now I'm afraid and scared even to take medicine.

Treating this fundamentally in such cases

Is there no way?

Any kind of procedure or surgery

I am curious if there is such a treatment method.

Not an injection or medication prescription

I want to know the treatment options.
