In a lengthy post, the 29-year-old urged fans to get tested and shared her own experience with the tick-borne illness.

"I was diagnosed a few days ago and have a long road ahead of me. Supposedly you get it from ticks but I have absolutely no recollection of being bit or having a rash or ANYTHING," Crystal captioned the photo of a vial of ticks. "Most importantly there are SO MANY of you carrying Lyme that don't even know you have it."
