I am scared of getting an infection from the hospital. Am I overthinking?

Hello doctor,

I had an ENT examination and the specialist did not use gloves but, did not touch the part going into the nose the first time. The tubing, the second time it went up my nose, was touched at the bottom by her at the light. I am very OCD usually and watched this happen but, somehow trusted her as she is well respected. She had used hand sanitizer when she came in but shook my hand. Having been at another doctor's myself prior and registering my thumbprint on the check-in, I did use hand sanitizer twice after. But, I was holding a clean plastic cup from the water cooler with what I believe, was a clean tissue to hold the cup. She then did the procedure the second time having touched the tip of the scope with the fingers. She wrote back to me saying she will change her ways.

The PCP is under the same system and asked me not to worry but, agreed to do the testing when I pushed. What tests should I have? Should I wait to get symptoms? Again, I am not sure she even used the wall sanitizer. I am asking the PCP to do an HIV and MRSA test. What else should I have her test me for? I am not vaccinated against Hepatitis B. Should I ask for a TB test? Does a general staph culture exist to rule out colonization? I work with children in talk therapy. So, I want to be sure I do not have anything communicable. I know it is hard to tell. But, I am panicking. What tests would you suggest? In what priority? Please be kind. I am already blaming myself for not speaking up. I can barely get up in the morning. I anxiously await your response. Thank you.

Thank you doctor,

I was on broad-spectrum antibiotics for 20 days. First, for a molar extraction and then for nasal swelling. I was taking 875 mg twice a day until four days before the ENT exam and a course of 500 mg twice a day for the extraction, and the gum graft was still open and healing. So was that a possible entryway? Is there a general test for staph colonization in the nose? I do not want to spread anything to my patients while exchanging paperwork, appointment cards, and playing games with the children in therapy. I appreciate what you are saying regarding OCD but, what communicable disease could I have gotten that would spread to family or patients, through close skin contact given the situation? What about TB? If the doctor shakes hands with all her patients and only uses hand sanitizer before, could she not have touched a contaminated tool or hand prior and spread the contamination to the tube that went into the mucosal lining of the nose? Why do doctors wear gloves typically then or use a sanitizer at all if there are no communicable risks? I really want to protect those I love and work with more than just worry about myself. I am only looking to prevent the spread of anything to others. I look forward to your reply.
