I know it's painful but poor nutrition (or lack of nutrition) seriously affects overall healing.

SO... Buy a high protein powder. Add milk or almond milk and blend.

I know it's painful to drink

so ask for magic mouthwash, swish and (if you can - swallow - I say this because some of them are made to be spit out... some you can swallow) otherwise spit it out.

this will numb you. Then CHUG your smoothie.

do this 2-3 times a day. and supplement with the boost.

Also if you are cancer free. Take a good multivitamin daily, and maybe some vitamin d and c. (ask your dr if this is okay.)

after you down your smoothie/boost. brush your teeth, waterpik them with luke warm water (replaces floss - freshens and cleans) then take a spoonful of manuka honey and let it melt in your mouth. swish for about 1 minute. Swallow. this is antibacterial, anti inflammatory, and fights infection. It stings at first then numbs and soothes.

Keep your mouth as clean as possible.

If you don't have a waterpik i advise getting a deluxe one and use it on the lowest setting with the tongue cleaner (looks like a little spoon) it is terrific for cleaning and has different levels of force.

hugs and best of luck.
