It is important that you get evaluated by a medical professional who can take a detailed clinical history, perform
a physical examination, and order any necessary laboratory and/or imaging tests. While it is possible your symptoms may be related to compressed nerves, it is also important to rule out vascular problems. For example, aortoiliac occlusive disease aka Leriche syndrome can present with the clinical triad of erectile dysfunction, pelvis and thigh claudication, and absence of femoral pulses. Risk factors include hyperlipidemia, hypertension, diabetes mellitus, and smoking.
Minimal pain urinating now, but still feel like I have somehow lost my "control" of my PC muscle, so whenever I try to tense it, I actually tense my spincter instead. I have tried to stop my urine flow with the muscle but I can now only stop it for a few seconds, so I'm guessing it's weak and might need some kegels, followed by reverse kegels, because it is also probably tight.
Are you still having pain urinating? How are you feeling now?
You probably did just pinch a nerve or something, but if this lingers more than another day or so, see your doctor. No one can diagnose you online, but pain is always an indicator that something is wrong.
