Therapy for Grandpa

Let me tell you about my grandpa  Robert LeMay. My name is Cami and I am one of the eight grandkids that wants their grandpa back to the way he was before his open heart surgery. Those were the days of fun filled family get togethers, great holiday dinners, spending time playing games around the dining room table and knowing how happy my grandpa was being with all of us. 
       That all changed November 7th. During his surgery there were several serious and life changing complications. Although it’s been almost two months since his operation recovery is slow and it will be a long long road. Grandpa can’t eat due to the muscles in his throat being partially paralyzed. He has a feeding tube and needs extensive therapy to try and get the muscles in his throat to work again.  He also needs a lot of physical therapy to get him walking again. My grandparents have health insurance, but much to my surprise I found out today that a lot of the medical bills and ongoing expenses towards his therapy and recovery will not be covered. I want to help my grandpa to have the BEST chance for a full recovery.   Can you please help ?   Thank you very much if you decide to help.  And prayers are greatly appreciated as well.
