Help Christian get the medical care he needs

Christian is 9 years old and was just diagnosed with Eosiniophilic Esophagitis (EOE) which is a chronic, allergic inflammatory disease of the esophagus.  It is very painful and he has a hard time eating or keeping food down. 

Despite having insurance, his Mom Renee is having to pay out of pocket 20% of the exploratory surgeries he has to have every 3 months, co-pays, medicines and alternative treatments that they are trying which are not covered by insurance.

Renee herself is recovering from surgery right now and will be out of work for a month a half.

Any help you can give to this single Mom, and this special boy, is very much appreciated.
God Bless!
