[|Human|] Hi I have a kidney stone and currently under hospital for it however they are just advising me to drink fluids.. I have increased my water intake to 4litres a day and as a result I am visiting the toilet more.  In addition I have noticed that the tip of my penis is getting red blotches on it.  On the days I dont drink as much water I dont seem to get these but when I ensure I drink regularly I get the blotches back.  I am not sexually active at present.  I am 36yo male, 5ft 11 and 207lbs
[|AI|]  Red blotches may be due to inflammation which is called balanoposthitis, and it is painful and occurs in diabetics and is like bell sound of elephant(diabetes) coming after. So check your fasting blood glucose if you are obese, and you said increased urination which is occurs in night is also a symptom of diabetes. If your blood sugar is normal consult a physician for local examination of penis to rule out other pathology.
