Psychological Pain

Is it possible that if you hear so much about a certain disease, you can think you have it, even feel the pains, when you know you don't? For example, before last Monday, I had never had any testicle pain. Then on Monday in school, we watched a video on testicular cancer, and since then, I've been feeling occasional pains in my testicles.

Thanks

You are not alone! I get paranoid with every possible desease and then some time later I just forget about it. It'll pass.
