Hi welcome to Healthcare magic forum. If it is really T.B.gland diagnised by needle biopsy
or excession biopsy , he must use full course of anti tb drugs , as there may be a spread of infection from the glands to the other tissues like chest, the most commen site, bones, intestines, or brain all these if it is confirmed only.
If it is not confirmed , it could be due to any other cause like head lice
in the head, throat infection
Convince him showing this reply to him. The treat ment also is not combursom it can be as easy as he want, if he dont want to have injections he can avoid them, there are combination packs to select according to his choice.
Wishing that he will be convinced with this answer, i thank you for calling.
