Sick and Hurt

while there are pluses to having moved into my new place, there are definately minuses as well. like since we moved, one of us, whether the baby or just someone in the household, has been sick or injured. i clean, i use pine sol bleach and lysol... but just keep catching bugs. i dont think ive felt well once since i moved in.
i hurt my back the other day, after waking up not being able to turn my head. went to put baby pants on, and wham.. back spasms. ive hurt my back before. ive hurt it alot. and im usually constantly stiff or sore in some way or another. but this time scares me. this time, i didnt just go to the chiropractor, and have it be fixed.
i had spasms... where it would drop me to my knees and bring tears to my eyes.it seems to be getting worse every time. cause usually, i go in hurt, come out still hurting, but in a day or two its gone and i can resume daily activities. well i went to shovel my horses stall today, and OUCH. it didnt totally hurt, but i could feel, that if i pressed any further, it would spasm out and i would be left on the ground. ive never felt that before like that. like im weak and broken. im not sure what to do about it. no medical. and really? there isnt anything anyone can do about back pain besides crack it and give pain killers. sure, stretch.. ice.. heat.. but sometimes stretching is what pulls it out. so what do i do? i need to work. its SCARY.
