The Bachelorette alum JP Rosenbaum has shared an update on his health crisis, and it appears he's having some "brutal" side effects from his treatments for Guillain-Barre syndrome.

"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.

People with the condition, which reportedly affects about one in 100,000 people a year, typically need to be hospitalized for days or even weeks.

Ashley wrote Sunday on Instagram that JP was "doing well" but may have "a long road to recovery."

Part of that road to recovery apparently includes both physical and occupational therapies, says JP.

JP, however, said in Tuesday's Instagram video his migraines had subsided by that point and he's hopefully just going to continue to improve.

While JP rests at home, his family is apparently supporting and taking care of him.

In the video, Essex was shown playing doctor in her dad's bed.

"This one helping with recovery and smiles," JP captioned the sweet clip, before saying, "Good to be home. Essex is doing her own physical examination to make sure I'm okay."

JP and Ashley fell in love on The Bachelorette and then got married in December 2012 in a ceremony that aired on ABC and was officiated by franchise host Chris Harrison.

The couple renewed their wedding vows in Aruba in August 2018.

Just last week, JP posted a sweet message to his wife on Instagram, wishing her another happy wedding anniversary.

"7 years down, probably about 3-4 more to go," JP captioned a family photo.

"Happy anniversary to the woman responsible for all the love and happiness in this picture (and basically all my pictures for the last 7 years). [Love] u @ashleylynnrosenbaum."
