The mystery virus that Silverchair frontman Daniel Johns came down with is causing a rare strain of arthritis. Docs put him on antibiotics to combat a virus which provoked the reactive arthritis. Silverchair manager John Watson revealed, “Daniel’s not being cured for arthritis, he’s being cured for the virus. Once the virus goes away, the arthritis will go. It’s temporary but it’s still painful, and the swelling can be a sight to behold when he has a particularly bad day.” Heraldsun.news.com.au has since removed the article.
