Hope everyone doing good!

It is almost 3 months from my last radiation.Trying to recover from infection still on antibiotics.Meeting my surgeon every week for this,he told me not to worry it will heal after some time.No saliva secretion due to which chewing is not possible.Want to gain some weight badly as i lost huge one.Taking semisolid fluids by mouth no feeding tube, planning to do some physical exercise like cycling which is my favourite.

Someday i feel negative, i know i have to be positive, even though.

Now do i have to go for a PET scan ?any suggestions please

Thanks alot for your kind support and wishes.
