I have had CT's Ultra Sounds and the works. They all show nothing. The pain comes and goes. Sometimes it's while working out and sometimes it can come simply by sitting on the sofa. Laying in the fetal position relieves the pain but the pain is still there. I usually have to go to bed, wake up and it's gone. Standing up straight is not good. When the pain is present, if I try and stand up it feels like a string is connected to my belly button and my penis. THere is also a slight dull pain in my right tesical. No hernia though, I just got back from the doctor who says there is no hernia present.
