Well to start my problems all began last weekend where i was in a store bending down to check out some items when all the sudden i kept getting these heart palpitations which scared the **** out of me. So i went to the doctor the next day to tell him my problems and he told me it was and stress which i guess it was cause it stopped after leaving his office with the clarification that it was nothing to worry about. So after that i decided to really start watching my health more because i hate having the feeling of being sick so since at that time or last Monday i was on a ketosis/atkins diet i decided to stop it and just eat whatever the heck i want(health food wise)and i felt good all that day(last Monday)but the next day i started to get this brain fog feeling and heavy headness feeling along with a slight fever of 100 point something and and now yesterday and today i started to have a stiffness in my neck which i think may be caused by sleeping on the couch and a sort of sharp pain in the left side of my head (behind the left temple but above ear) but only after trying to pull myself up over a fence(dont ask) but the pain seems to have gone away only after a few mins. I also have a slight feeling like there is something in my throat but not to bad since i dont notice it unless i think about it. Well thats about it please help me i am really scared that it is a brain tumor or something cause that is just the way i am.

Thanks for the help,
will
