I had a co-arc repair at 18 months, been healthy as a horse for many years. Always have taken pre-antibiotics about 6 amoxicillin before any procedure or appointment. I got a tattoo on valentines day without taking premeds, now I m experiencing shortness of breath, heavy chest, very tired, chills (cold), light headed with headaches The only issue is that I have severe depression and high anxiety and I m sure if I m having a panic attack.
