Please help me recover my cancer recovery expenses not covered by my health insurance

On March 31, 2020 I was diagnosed with T4 N1 Nasopharyngeal cancer and endured thirty-five radiation treatments (of 70g which is pretty high strength). My last treatment was on June 8, 2020 and I'm now in the 'recovery' stage.

Being a Head & Neck cancer, I've endured several side affects from the radiation treatments but thankfully after four months, most have subsided except for some dry mouth irritation and lymph node draining during the night because I'm laying down. Hopefully that will also pass in due time. They tell me it's all about 'time' in the recovery stage so with continuing daily management, this should be resolved as best it will ever get to be by end of this year.

However, it turns out that because all of the recovery period daily care needed is managed with over-the-counter products, my health insurance won't cover these expenses, even though it's directly related to the cancer diagnosis and is needed to recover from the disease. Makes me wonder what I'm paying almost $200 a month to my company's health coverage. I've paid out-of-pocket expenses for the following products: ZylaMelts (40 discs at $17 per package and produces saliva during the night), Prevident 5000 toothpaste (which I'll have to use the rest of my life and expensive at $15 for a small tube), Aveena moisturizing cream to heal the radiation burn on my neck, Alpha DME coconut oil for dry lips and healing neck area, fluoride trays to use for applying daily fluoride to prevent cavities (as radiation can cause serious cavities down the road), small humidifier to help with dry mouth during the night, mucositis mouth rinse, amoxicillin, peridex rinse and a waterpix. All of these products were required to get through the recovery period without further complications (which would have definitely gotten worse if not properly managed on a daily basis).

Being I'm a senior receiving the usual OAS and CP credits these treatments used up a big chunk of money so, although times are really tough for all of us, it would be so very much appreciated if you're in a position to help me recoup these expenses. My recovery is going really well and am going for my second MRI on November 9, 2020 with the hopes that they'll see the tumor has been defeated and is no longer there....that would be wonderful news although I'll likely always need to be monitored for its possible return.

Thank you all so very much for being so supportive during the past seven months as it's really kept me in a positive frame of mind!
