Dear Patient,
I do not think that the pain in the middle of the night is related to the event of the last night. Keeping the urine for 20 minutes normally should not produce extreme pain big enough to wake you up during sleeping.
Of course that having strained the muscle may give you pain, and maybe you strained the muscle during holding the urine.
What I suggest is to wait for 2 more days. If you experience again the pain, or other symptoms please go and make the urine and blood analysis, to check for
prostatitis, uretritis or any infection of the lower
urinary tract.
Kidney stones may give you pain also, but they are after localized in the back, lumbar region.
Meanwhile I would suggest You drink 2-3 liter of water a day, so if there is any infection, a lot of water will alleviate it.
Please feel free to write me anytime, and thank you for choosing HCM.
All the best,
Dr. Eni
