Dealing with Panic Attacks Triggered by Medical Procedures

Hi, I'm pursuing diagnoses for Anxiety Disorder(s) and ADHD and I also have cerebral palsy. I've had two panic attacks in the last 5 years, both triggered by merely reading about seemingly minimally invasive medical procedures (enemas and acupuncture respectively). The first one I experienced came with nausea, faintness, cold sweats, and I was luckily able to stop it and keep myself safe, as I was isolated at the time. The second time was more intense: faintness, nausea, blackouts, disassociation from my body, all lasting a few hours. I've had multiple surgeries as well as other "less invasive" treatments for my CP, like Botox injections, hyperbaric oxygen therapy and ESTEM therapy. Has anyone else with an extensive/traumatic medical history experienced panic at seemingly innocuous quasi-medical triggers? Could my body be carrying trauma from the partial-sedation Botox injections or something? I should add I'm okay with vaccines, tattoos, piercings, other small needles and things like pipettes in my orifices. 😳 What caused the panic? Anyone?
