Here's a little something on mucositis:
---------------
Mucositis is the painful inflammation and ulceration of the mucous membranes lining the digestive tract, usually as an adverse effect of chemotherapy and radiotherapy treatment for cancer.
Oral and gastrointestinal (GI) mucositis can affect up to 100% of
patients undergoing high-dose chemotherapy and hematopoietic stem cell
transplantation, 80% of patients with malignancies of the head and neck
receiving radiotherapy, and a wide range of patients receiving
chemotherapy. Alimentary track mucositis increases mortality and
morbidity and contributes to rising health care costs.[1]
For most cancer treatment, about 5-15% of patients get mucositis. However, with 5-fluorouracil (5-FU), up to 40% get mucocitis, and 10-15% get grade 3-4 oral mucositis. Irinotecan
is associated with severe GI mucositis in over 20% of patients. 75-85%
of bone marrow transplantation recipients experience mucositis, of
which oral mucositis is the most common and most debilitating,
especially when melphalan is used. In grade 3 oral mucositis, the
patient is unable to eat solid food, and in grade 4, the patient is
unable to consume liquids as well.[2]
Radiotherapy to the head and neck or to the pelvis or abdomen is
associated with Grade 3 and Grade 4 oral or GI mucositis, respectively,
often exceeding 50% of patients. Among patients undergoing head and
neck radiotherapy, pain and decreased oral function may persist long
after the conclusion of therapy. Fractionated radiation dosage
increases the risk of mucositis to > 70% of patients in most trials.
Oral mucositis is particularly profound and prolonged among HSCT
recipients who receive total-body irradiation.

Because I had received 5-FU and Cisplatin with the radiation I had grade 4 mucositis after treatment. It lasted about 4 weeks then went away. Guess I got lucky.
