Award-winning songwriter Sturgill Simpson tested positive this week for COVID-19, he said in an Instagram post.

The diagnosis followed roughly a month of symptoms, the 41-year-old singer outlined in his post. Simpson said he first visited a doctor March 13 with COVID-19 symptoms, one day after promoter halted his North American arena tour with Tyler Childers.

Simpson toured Western Europe late January and early February, before kicking off the North American tour Feb. 22 in Alabama. The tour played Southern and east coast states before hitting pause March 12.

His initial symptoms included fever, chest pains and "pre-stroke blood pressure levels," he said in the post.

On his March 13 doctor's visit, Simpson said, "I spent an hour listening to a (highly condescending) Doctor refuse to test me because I 'did not fit testing criteria' and tell me why it was impossible that I had contracted the virus due to its extreme rarity and that it was not in western Europe yet during that same period (which we now know is incorrect) even though I was told by two nurses that I was the first person their hospital had walk in requesting to be tested."

In the post, Simpson shared his frustration with COVID-19 testing and information provided by the White House.

On April 6, Simpson said he found a free drive-through test in Alabama, receiving a call four days later that he tested positive. Simpson's wife, who he said has been by his side since the Europe trip, tested negative.

"Yesterday on Friday April 10th, after almost one month without any symptoms, I received a call from the Nashville CDC stating that my test resulted in a positive detection for Covid-19. My wife (who has been by my side since Europe) tested negative."

He later added, "But hey, at least our Government appointed task force headed by a man who does not believe in science is against mass testing and we now have a second task force in the works to 'open America back up for business'!"

Simpson said he's quarantined until April 19.
