"Clearly I have not changed or showered in a while," JP said in the video.
"But I'm resting comfortably at home. This morning was pretty brutal, I had some pretty severe migraines. I've never had a migraine before and these were just incapacitating. I couldn't move, talk or anything. It was rough."
Migraines are apparently a side effect of the intravenous immunoglobulin treatments, known as IVIG, he had received while in the hospital.
JP and his wife Ashley Hebert, who accepted a marriage proposal from JP on The Bachelorette's seventh-season finale in 2011, revealed on Sunday he's been diagnosed with Guillain-Barre syndrome in which the body's immune system mistakenly attacks nerve cells.
JP explained earlier this week the condition makes it difficult or nearly impossible to pick up the phone, button buttons, tie shoelaces, put on deodorant, and play with his two children -- son Fordham Rhys, 5, and daughter Essex Reese, 3.
According to WebMD.com, Guillain-Barre syndrome can cause muscle weakness, reflex loss, and numbness or tingling in parts of the body. While it can lead to paralysis and permanent nerve damage, most people tend to recover, even those with severe cases.
