Male, 20s
My experience was great. I was worried, but the symptom checker helped me narrow down what it might be. I feel a little relieved compared to when I first started, and it gives me a starting point for what my symptoms could mean.

The questions asked and possible causes seemed spot on, putting me at ease for a next-step solution.

Female, 40s
I was actually very impressed with the results it provided because, although I didn’t mention it during the questionnaire because I thought it was unrelated, it suggested I may have something I’ve actually been diagnosed with in the past.
