Hi, I'm a 16 year old male and I can't get my head around this problem. When I go to the toilet, it takes so long to finish peeing. I would also like to add it burns and feels like I haven't completely 'emptied'. I consulted my doctor and she diagnosed me with a UTI. To treat this she gave me some Efferscent Powder (dissolves in water) and take this up to 4 times a day for 5 days. The first couple of days it increased my urine flow a lot and got rid of the burning. But after about a week the symptons and slow flow has come back?
