Josh Abbott had a health scare over the weekend that landed him in the hospital.......

Abbott explained the ordeal that forced the band to cancel their Las Vegas appearance on Saturday, July 23.

Here is what he had to say.....“Currently in the hospital. I called one of those hydrate IV guys to come set me up a few hours ago… Everything was fine w/ the saline and vitamins, and then towards the end he added glutathione,” he shared in a tweet. “Well it turns out I’m DEALTHY ALLERGIC to it and my asthma kicked in. It got real bad real quick. Couldn’t breath. I thought I was seriously about to die. EMS was worried I’d go into cardiac arrest. Got a nice fancy ride in an ambulance on a stretcher. Crazy… I can’t even explain to you how bad it got but I’m grateful to be here. It was that bad.”

He updated fans later with his official diagnosis of Anaphylaxis which is a severe allergic reaction.

He was discharged from the ER later that day. He also assured fans that the group planned on making up the missed date later this year.

Let's hope that Abbott will be back in good health in time for their next scheduled show this Thursday, July 28 in Memphis, Tenn.
