Mostly like ibuprofen and excedrin. I tend to get headaches and thats what I use. I switched to excedrin when ibuprofen didnt do anything anymore. Anyway, I had never before had trouble swallowing any of the pills before. Now I can not seem to swallow them without trouble. I use to be able to just use water, but now i need to use something thicker be it juice or milk, just something thick. This just starting happening, I'd say within the last 3 months. But before that I had no trouble swallowing them whatsoever, and now I just can't figure out why I have so much trouble as of now.

Any help would be greatly appreciated. Thank you.

This is going to sound really wierd, but please hold off ringin the mental home for just a sec. When i was about fifteen i was sitting outside my country house holding a match because me and my mate were mucking around with them (I know, bad idea). I was holding it about 2 inches away from the box, and my step dad came out and told us to stop because we would cause a bushfire. when he went inside i got angry and the match, not just the head but the whole thing wood and all, just burst into flames in my hand causing me to burn my finger and almost cause a bushfire. Nowadays when i am in the kitchen or bathroom the tap will turn on by itself, then back off again. And ceiling lights (the ones that hang from a cord) will start rotating, then when i look up they stop and start rotating the other way. i try to pretend its not happening and it stops for a while, but it always starts again.
Always had strange liking to water, fire, and had dreams of being able to control them both. Need Help!!
