My husband is 8 weeks post treatment and he still has copious amounts of phlem which is keeping him from sleeping or swallowing, he would like guidance on when it may stop or encouragement. The docs say next to nothing or are so vague. Does the phlem mean the radiation is still working, why does it keep coming. Some people on here have said theres stopped at 3 weeks so he's discouraged. I try to get him to focus on the good things like being finished with treatment but he just wants to get better and it's hard for him to be patient.
