Fracture?

[prib1]

I had my first shot of the third Round  of Xiaflex on Wed. First time without any bruising.  I thought I would start the RestoreX a little early and more aggressively on Friday night. On Saturday morning I woke up with an erection and then I felt a pain, no pop but sudden swelling and bruising. Pain was only about a 4. Looks alot worse than it feels. I called the Dr on call and he said If I could get an erection the tubes were okay and no need to go to the ER. Well, that was the last thing I wanted to try but after about 5 hours I gave it a try and was able to get a good erection considering the situation so I am assuming the tubes are good and just broke a blood vessel, does this sound right? Pain is about a 2-3, swelling is a 5-6 and bruising  is  4-5. Thanks
