Do not ask strangers for medical advice.

Talk to your doctor.

If you feel uncomfortable talking to your doctor, get a new fucking doctor, because they are there to help you with health issues.

Strangers on the internet do not know your medical history. Strangers on the internet are just that, strangers. They do not have any incentive to give you well-informed advice.
