Hi Deborah,
My husband is also 8 weeks post-treatment and is still spitting phlegm every few minutes. We keep a garbage bag-lined bowl right next to the bed so he can just rollover and spit. Swishing with a sterile water/baking soda/salt solution helps thin out the secretions a little. My husband's phlegm is a yellowish color and we are trying to find out if this is normal or signals an infection.
If you haven't already read my long post in this category "seeking advice for husband-1st time post, I would recommend reading the responses. I got some very good information from others. Also, I pulled up Brian Hill's interview with a reporter from Dental Abstracts Magazine and it was very good. It made me realize that we are not in the sprint just to get through treatment, but are now running the marathon that recovery seems to be.
