The coughing could be coming from her smoking. The smoke could be irritating her lungs. I have not smoke for a little over two years. I loved to smoke, but now if I am in close quarters with someone who is a heavy smoker, I start coughing. I can feel it in all my chest. I am a loan officer and interview people. Some of the smokers that come into my office, well it just just bothers me so much. I start coughing and it can be very embrassing. Its hard to do my job at times.
I sorry that your Mom is also having to deal with her job and the insurance issues. Hopefully the attorney will be able to help her.
Best Wishes,
Dee
