My boyfriend has gone to get his results... confused

On Wednesday my boyf told me he may/has a brain tumour today he has gone to find out the results... he wouldn't allow me to go with him and support him.. I feel as though I really want to be there but I don't want to cause a fuss as he is unwell... I really don't know what to do.. he also mentioned he may have to have injections depending upon the results... haven't heard from him in an hour I am sooo worried... I don't know what to do or who to talk to.
