Troube urinating. Can't pee very well after drinking lots of water

A few weeks ago, I have the urge to pee. But I hold on to my pee for a very long period of time until I feel a sharp pain in my bladder?

Then I went to the toilet and pee and release the urine.


But after that incident, I feel something wrong. Now when I drink lots of water, I can't seems to pee. And even if I pee, the urine stream is weak,slow and not much urine comes out.

Now, I always wake up in the middle of the night to pee.


I'm very scared and worried.

I'm scared and worried that I may have urinary retention or weak bladder muscle or bladder damage.

I also feel pain in the left and right side of my abdomen.

I'm seeing a urologist in 2 weeks time. But I'm still very scared and worried.


Right now, I also have flu and cough. But I'm not recovering well after seeing many doctors and taking the medicine.


Can it be due to my urinary problem that affects the recovery for my flu and cough?


Is it because I can't really pee well, so when I drink the cough syrup, my body can't flush out the virus, bacteria?
