I'm 42 yrs old, have had numerous injuries in my lifetime. I have chronic back/neck pain due to those injuries and I also have asthma. I recently moved into a house where there were cats...I'm fighting the battle to get rid of the smell/ammonia/bacteria...Since I've moved in here I've been experiencing more breathing problems...strange numbness/tingling in my face/arms/hands/legs/feet...i've experienced these things before but never all at once...could this be the problem or should i be worried about a heart attack or stroke?
