Quick Dad update
He is back in the hospital tonight. Has been there since 5ish AM Sunday, Mom drove him in to St. Vincents (closer to where they live now as well as me and Lisa). He went in for the same reason as before, throwing up everything and a sharp pain in the middle of his shoulders.
This time, this hospital did a CT scan and found a lump in his esophagus. Its caused by an artery being wrapped around the wrong way (yup, thats dad) and causing the inflammation.
They are keeping him overnight to keep an eye out and have him on fluids and Prilosec. No news on when he will be sent home.
