Need help covering costs

Hello friends,

I wanted to recap where things are with me.  I currently am stage 4 Pancreatic cancer with metastasis to my liver. It is not operable, I currently am surviving on my chemo treatments. 

Let's rewind to 2016, I had a total knee replacement surgery on my left side.  By 2017, it completely failed and I had to undergo a total revision surgery.  Between 2017 and now I have undergone multiple manipulation and physical therapy sessions. I went to see another surgeon at Stanford this time and without going into great detail, the revision has failed as well.

I am having surgery on July 30 to correct this, making this the 3rd time under the knife for this knee.

I humbly am asking for help as there is medical equipment that is not covered under insurance that I just can't afford. It is not a lot of money, but as a father of 4 still at home on SSI I just can't afford it.

Thank you for taking time to read this, and know that I will find a way to pay this forward. God bless you all,

Craig.
