Hi 

Need a bit of advice, I am a 23 year old male and I am showing all the symptoms of one of these two. I am able to wee 4-7 times a day but I have to sit on the toilet for sometimes 15-20 minutes at a time before I can go. I don't experience any pain when peeing just difficulty going.

I had this problem about 8 months ago but they didn't diagnose me with anything, and I cut a lot of caffeine out of my diet but it now seems to have re appeared over the last 7 days.

I have done a lot of reading and the most likely outcome sounds like acute prostatitis because of my age and symptoms. (Which sounds the best option compared to BPH etc etc)

I have two main questions really:

If I had BPH would my prostate fluctuate in size, because I have been fine for the last 6-7 months. 

Would also like to know if there is anything I have missed or if it could be something else?

I am going to doctors to today to book an appointment.
Thanks
