A patient came in last spring convinced she had a stubborn case of eczema. She'd been buying every cream the pharmacy shelf had to offer for months. The rash wasn't eczema at all — it was a reaction to a new laundry detergent, and it cleared in two weeks once we figured that out.
That's the thing about skin conditions. The skin is loud, but it isn't always honest about what's wrong. As an internist here in Los Angeles, I see a lot of rashes, bumps, spots, and itchy patches — and a good chunk of the time, the first job is simply sorting out what we're actually looking at.
Why see your primary care doctor for a skin problem at all?
Because your skin often reflects what's happening inside you, not just on the surface. A new rash can be an allergy, a side effect of a medication, a sign of a thyroid issue, or something that genuinely needs a dermatologist's eye.
In my practice, I start with the whole picture. What changed recently? New soap, new supplement, new stress, new travel? I look at the pattern, the timing, and the rest of your health before deciding whether this is something we manage together or something that needs a specialist.
Many skin conditions are well within what a primary care doctor can evaluate and treat. Some aren't — and knowing the difference is half the value of starting here.
When should I worry about a rash or skin change?
See a doctor promptly if a skin change is spreading fast, painful, blistering, or comes with fever — those deserve same-week attention, not a watch-and-wait approach.
A few other things I tell patients to take seriously:
- A mole that's changing shape, color, or size, or one that bleeds
- A sore that won't heal after several weeks
- Hives that come with swelling of the lips, tongue, or throat — that's an emergency, not a clinic visit
- Any widespread rash that appears right after starting a new medication
Most everyday skin issues aren't urgent. But the ones that are, you don't want to sit on. When in doubt, send me a photo or come in.
What skin conditions can a primary care doctor handle?
Plenty of common ones — mild acne, contact rashes, dry skin, minor fungal infections, and flare-ups of known conditions like eczema or rosacea.
For these, I'll often start with a clear diagnosis and a simple plan: a topical treatment, a trigger to avoid, and a follow-up to make sure it's working. We have a page on topical treatments and dermatology referral that walks through how that usually goes. Sometimes the fix really is as boring as switching to a fragrance-free moisturizer and being patient.
Skin is also closely tied to allergies. If I suspect a reaction is driving things, sorting out the trigger matters as much as treating the rash, and that overlaps with how I approach allergic and reactive conditions more broadly.
How do dermatology referrals to Cedars-Sinai work?
When a skin issue needs specialist care, I refer you to a trusted dermatologist including Cedars-Sinai — and I make sure your history goes with you.
This is where being a small, membership-based practice actually helps. I'm not handing you a phone number and wishing you luck. I'm credentialed at Cedars-Sinai, so I can connect you with a dermatologist I trust, share what I've already found, and stay in the loop on what they recommend.
The cases I refer tend to be suspicious moles, biopsies, persistent conditions that haven't responded to first-line treatment, or anything where a trained eye and a dermatoscope simply see more than I can. There's no ego in that. Knowing when to bring in a specialist is part of good primary care.
A few habits that protect your skin in LA
Los Angeles sun is generous, and it adds up. Daily sunscreen, a yearly look at any moles you're tracking, and not ignoring changes for months are the simplest forms of preventive care your skin will thank you for.
I also remind patients that "it's probably nothing" is a guess, not a diagnosis. Most of the time it really is nothing. But the visits where it wasn't nothing are exactly why we look.
If something on your skin has been bugging you — new, changing, or just not going away — don't wait it out alone. Reach out and we'll take a look together, and if you need a dermatologist, I'll make sure you land with one of the good ones.
