Hi Andrew,
I'm ten weeks post and have various symptoms as you; they come and go.
YES -Ulcers/sores in mouth (along lower back of jawbone, started yesterday)
- occasional ear ache, with the feeling I need to clear pressure in it
- frequent pain in throat, especially after eating and swallowing a "solid" meal.
-occasional strong pain on my scalp if I move my hair around (for example running hand through hair)
-No fever

I called the MO on the scalp thing; they did not think it was neuropathy and suggested I take ibuprofen which works to knock down the pain.

My take is a lot of this stuff is "normal" along the path of recovery as our bodies are still weakened; our immune systems are still not working fully so some small bacteria take used to be banished now becomes a sore.

I am thinking that since I had two teeth pulled pre-tx that my chewing is compromised and I know there are times when I chomp on something it just grinds into my jawbone flesh and that has to make a sore.

Best to you, don
