Why is my penis itchy since Saturday?

You might have this problem if you are feeling pain when passing urine if you feel like you need to pass urine more often than usual, or when your urine looks cloudy. A bladder infection happens when bacteria enter the bladder. However, it is not usually serious. To cure it, your doctor might give you some antibiotics that can help kill the germs causing the infection. Ensure that you drink a lot of water to help wash away the bacteria. 

I don't recommend use of tadalafil without prescrition from a doctor. And if you are not diagnosed with any sexual dysfunction, it is not good to use medications. Tadalafil is a medication used to treat erectile dysfunction and pulmonary arterial hypertension. Only a qualified doctor can make an accurate diagnosis and prescribe the best treatment for you.

You may have two coexisting abnormalities in the scrotum area (one called hydrocele and the other called varicocele). These two conditions may give rise to discomfort and swelling, especially when you're on your feet for a long period. Hydrocele is the consequence of fluid buildup, while varicocele occurs when the veins are abnormally enlarged. Treatment can be topical or surgical if there is a need to operate. 

Your veins have still not changed from the way they were before the varicocele surgery 4 months ago. Varicocele is a scrotum condition caused by size-wise swollen veins. This can be manifested either in the form of painful swelling or it can lead to infertility. The surgery didn' t probably fix the issue entirely. Go back to your doctor and find out the reason this is happening and what further actions can be taken.
