Hi DD and in case I haven't already welcomed you to NeuroTalk, I am doing so now. I think from what you posted, that your MIL does in fact, have the nasty bug that is going around and she should be seen.

Anytime you cough up something w/color to it, there is congestion and infection brewing, or so my Dr told me. She may need antibiotics to overcome this. I am just getting over a nasty bug myself and Yes, it has added to my Fibro sx's. But, our weather is forever changing, and that really plays havoc w/Fibro too.

I thinks it's great that you are trying to educate yourself on your MIL's illness. Please tell the family members to take her to the Dr. Pneumonia is nothing to mess with.

Most MIL's would be happy to have such a caring DIL as you.
