Telehealth Is Real Medicine: What a Virtual Doctor Can (and Can’t) Do

There are still misconceptions about telemedicine. Here's what a board-certified physician can genuinely accomplish through a video call — and where in-person care is still needed.

The misconception: "You can't really diagnose anything virtually"

This is one of the most common things I hear from new patients — and it's worth addressing directly. A medical diagnosis is based primarily on history and symptoms. Studies show that in primary care, 70–80% of diagnoses are made from the patient's history alone, before any physical exam or test is ordered.

When I ask you when your symptoms started, what they feel like, what makes them better or worse, what medications you take, and what other health conditions you have — I am doing exactly what I would do in an office. The absence of a stethoscope doesn't change that diagnostic process for most common conditions.

What I can do virtually

  • Diagnose and treat infections (UTI, strep, sinus infections, ear infections, skin infections)
  • Evaluate and treat respiratory illness (bronchitis, flu, COVID, allergies)
  • Prescribe medications and refills (for non-controlled medications)
  • Order lab work and interpret results
  • Manage chronic conditions like hypertension, hypothyroidism, and high cholesterol
  • Provide medical weight management and GLP-1 prescriptions
  • Evaluate skin conditions (rashes, acne, eczema) — you can show me directly on camera
  • Provide sick notes, referrals, and documentation

When I'll tell you to go in person

I take patient safety seriously, and I will always be honest if a virtual visit isn't the right setting for your care. You need in-person evaluation for:

  • Chest pain, shortness of breath, or signs of a heart attack
  • Stroke symptoms (face drooping, arm weakness, slurred speech)
  • Severe abdominal pain
  • High fever with stiff neck (potential meningitis)
  • Injuries requiring imaging, sutures, or physical exam
  • Conditions requiring in-office procedures (ear wax removal, wound care)

I'd rather earn your trust by being honest about my limitations than overpromise what a virtual visit can do.

Not sure if a virtual visit can help?

Book a visit and describe your situation. If it's beyond the scope of virtual care, I'll tell you immediately and you'll receive a full refund.
