I have a very scary problem going on...Every time I have an erection it is in excrutiating pain...This started a month ago...I have looked up everything and ruled out a ton of stuff. I am not sure if its priapism because I can get hard and ejaculate with my penis then going down like normal in the flaccid state...100% positive it couldn't be an std. I did however a few times try out Cialis just to see what it does. This was 3 weeks ago and haven't taken anymore. I have gotten an erection probably 7 times since then and 100% of the time it is very painful but not in the flaccid state. Have no idea if a side effect of Cialis can do that this long? Its driving me nuts! If Cialis damaged or hardened my veins if my shaft it would have been erect longer than 4hrs but it wasn't. After I ejaculate it goes down like normal unless it happened during sleep?? Nobody knows and nobody has given me anything to take to fix this? I have heard methods of wrapping your penis in ice or rinsing it out with saline? Shouldn't a doctor be doing an ultrasound to see what is going on?
