Do I have a herniated disc?

I have been having really bad headaches lately. They usually come on fairly quickly. I would associate my headaches with the pain in my neck and shoulder, I just thought it was so bad that it radiated or something. Here recently I have been doing some research on herniated discs and I think that I might have one in my neck. My father used to pop my neck a lot to help with stress I was feeling and I found that popping your neck without a chiropractor could cause herniated discs. When I was doing more research on it I found that a bulging disc in between the C5 and C6 can cause chronic headaches and pain in the shoulder. Could it be possible that my headaches are just a side effect of a herniated disc in my neck?
