hello and welcome to HCM forum,
i appreciate you wrote to us, first of all i would like you to know that due to biting on a hard substance like bone, temporary headache might occur as a
referred pain.
For headache analgesics will be helpful, whereas for the ulcer ,if present on the
palate prescribe broad spectrum antibiotics, NSAID's and an antibacterial mouth wash(
betadine) to avoid secondary infection.
keep the patient under observation for a week,
also, oral multivitamins/antioxidants(once/day) will promote healing.
i hope i answered your query,
if you any further queries ,kindly post them.
