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.
