Early Monday morning I pick my 45lb bulldog off my bed to put him down and my girl and I go through our daily gym routine. I didn't stretch and got on a stationary bike. 20 Minutes later got on the elliptical. At this time in less than 2-3 minutes on the machine I felt nauseous and an "after getting flcked in the balls" feeling. Got on the treadmill and couldn't. We left. I went to Wal Mart and the feeling continued. It's not an "I'm going to die!" pain. It's a faint pain/feeling of after getting kicked. I slept it off over night. Yesterday I woke up and I was fine. Went through my day. Come mid day the sensation came back. Slept it off. This morning woke up with no sensation. It was fine. Went through my day. Come mid day again it came back. Don't want to move much. Now I've thoroughly checked both nuts and they're not tender to the touch. There are no changes in texture. No lumps or anything. Nothing out of the ordinary. It alternates. Monday it was my right nut, yesterday and some of today my left. I have a doc's appointment tomorrow. I am a bit scared. I don't want it to be the big C and have them do things to me I don't want. What do you all think it is? A lot of people think I pulled something at the gym or picking up my bulldog. Even the nurse that I spoke to on the phone to book my appointment said I must have strained something. Some people say hernia. Just don't want to go to the dock and get the worst of the possibilities.
