Jordan, in thinking back, I now remember that for some months after treatment ended, I had neuropathy in my toes. Because it eventually left me, I can tell you that it may not be permanent for your husband either.

As for the mucous, it just takes its own sweet time in stopping. I found that rolling up clean gauze to about the size of my little finger, and putting those rolls into the "gutters" of my mouth soaked up a lot of it and let me sleep for several hours, in a semi-reclining position. Because my mouth was so sore post rad and chemo, I also learned that Puffs brand tissues (without aloe) are the softest and strongest for wiping the gunk out. I know every patient has different experiences, but just about when I thought it would never quit, it just did. Like a switch was thrown. I hope it happens this way for your husband.

Although I have no experience with it, quite a number of patients have used a suction machine, which can be rented. You might ask if your husband's doctor will prescribe one. I seem to remember that some people have posted about Robitussin helping. You might search the forum for that. If I find it, I will let you know.

Finally, although the post treatment time can be really rough, don't ever lose sight of the fact that it will end, and things will get better.
