How do I know if I could have anaphylaxis from laser tattoo removal?

I have a full sleeve, full chest piece, half a back piece, and a stomach piece, and some of those are cover-ups. All tattoos were fine afterward apart from once, I was in the hospital in so much pain the next day, I think it was infected, they said tendinitis. I had a laser test patch 9 months ago, no redness, no blisters, nothing, it faded the ink, but after 6 days, I was sick for 2 weeks (cold/flu). Can I use lasers?
