Feeling feverish without having fever, all the tests are normal. (Tried heavy medication)
If I found a mosquitoes flying there, I jump out and try to kill them. It disturbs me alot.
Even there are no mosquitoes sometimes it feels like  they are there.

Something happend in past like and make conclusions it's going to happen again anyhown

Eg. Like after taking a cold shower if have got fever.

I have fear that taking cold shower will definitely going to make me ill.

There many people in my family which show some similar and different issue.

Q. Is it ocd or something different?

Q. Is ocd genetic?

Please document provide reference so I can learn more about what you are talking?

Please help
