Did you choke/cough when you eat or drink ? If so, it is possible that some of the food or liquid is going into your windpipe/lung and causing infections in the respatory system. This is the problem I am dealing with right now, I saw a speech therapist two weeks ago and found that I had problem with my swallow.

I did not have any problem with breathing but I do have low fever. Most of the time, it is between 99-100F, I did not feel the temp at all, but it is there. I am trying to adjust my diet as the first step, if it does not work, I will have swallow therapy soon.
