Is it normal if I feel one of my testis is bigger than the other? I touch it and I can feel a lump in the right one. I used to have an acne problem on my testicles and they itched. But the issue has since been cured by an ointment given to me by a doctor. Do you think my current problem is still related to the previous acne condition, Doc?
Doctor, why does thin white liquid often flow out of my penis, although it is not erected?
These 2 days, my urine is foaming. My frequency of urinating is also reduced, only around 3 times a day. I drink a lot of water but the problem persists. Why is this so, Doc?
Doctor, why do I urinate 15 times a day? Sometimes I cannot hold my urine. I don’t feel any pain around my hip and lower left abdomen. Why is this so, Doc?
On my penis shaft, there is an open bump, with pus. I googled and found out that it is an STD. But I have never have had sex before, Doc. This has been 4 days. Can I apply some ointment so the wound can dry up soon?
Doctor, I have a problem with narrowing of my urinary tract. I have 3x stents, and now my kidney is swollen, grade 3-4, and there is a simple cyst in my kidney and the kidney is thin. I was advised to have the kidney removed, even though previously I was only advised to get the narrowing tract cut. According to my doctor, there is to no point in keeping the kidney because there is a simple cyst. Also the function of my kidney is good enough at my 64 years of age and creatinine level is at 0,90, so I should be fine with only one kidney. My question is, what if I keep my kidney, and only have the narrowing tract cut? If I have my kidney removed, are there any possible further problems? Please give me your advice. Thank you
I have pus in my urine these 2 weeks. Besides taking antibiotics, what treatment should I do, Doc?
These past 2 years, I have been feeling pain after urinating. I saw a urologist but there is no improvement. Now I feel like there is still urine left over although my urine stream has finished. What disease is this, Doc?
Doctor, please help, what is the likely cause for pain around the testicles? Thank you
Dear Doctor Colin Teo, I am 20 years old and just had a circumcision done due to phimosis, the foreskin has been removed completely and the scarline is about 3mm away from the glans resulting in a ”low cut”. I am very terrified and worried that I will lose a lot of sexual sensitivity/sensation, because of the cut being so low instead of being high where some of the foreskin gets preserved. Is there a significant difference in sensitivity/sensation between a high and a low circumcision cut as? Is it true that at least 1-2 cm of foreskin has to remain after circumcision in order to preserve maximum sensitivity? Thank you very much!
