Left testicle has been hurting throughout the day. Not terrible pain, more so an aggravating pain. That side also feels a little tighter than the right. I did it last night, but wasn't that rough. I hope nothing is majorly wrong. What could it be?
Sounds like you have prostatits or epidydmitis.
NSAIDS will help discomfort, but you will likely need an antibiotic if it is above. Tight briefs limit movement and discomfort (if epidydmitis). If prostatits, ejaculation helps, but may be painful or even blood-tinged
If stable can wait until mon,
unless fevers, worsening pain, or skin changes overlying said testicle --> urgent care vs after hour clinic vs ER
If you are in BR area, I can see you Monday fwiw (urologist here)
