Ex-NBA stud Jason Collins has tested positive for coronavirus ... and he says he feels so crappy, he's considering a return trip to the hospital Tuesday.
The 41-year-old former center says he took a trip to New York City earlier this month for the Brooklyn Nets' pride night game on March 4 ... and believes he contracted COVID-19 while there.
Collins says his symptoms started with a "terrible headache" just a few days later on March 11 ... and then quickly progressed.
"A few days later I had a fever and then the cough," Collins said.
