Bactrim and mistake

i've been on bactrim dm for about a week now (2 doses/day for 14 days) for a possible MRSA infection (should know the results tomorrow...hopefully). about 2 or 3 days into it, i felt extremely lethargic and achy (all my joints were sore and almost 'warm'). woke up in the middle of the night a few days ago with my entire tongue feeling numb and the base of my skull hurting like hell and my lymph nodes on the back of my neck swelling and sore to the touch. since then, i've had chronic pain in this area. after reading some of the posts here, i decided to stop my dose until i could speak to my doctor since i wasn't able to speak to him yet today, i decided to resume bactrim until i can get on something else. it's a terrible feeling being trapped between treatment for a potential MRSA infection and stopping treatment because of the possibility of serious side effects. i just took another dose moments ago and am honestly worried i've made a mistake. but what choice do i have when faced with the possibility of an infection that is also very serious? i can't do nothing...

i honestly don't have a lot of options with a MRSA infection...i see people on here mentioning cipro or levaquin, but these also have tons of posts on here about crazy side effects.

this past week has been a living nightmare...

i hope those of you who have experienced such terrible problems with bactrim will find something that helps you...
