Four-Week Skin Check

Stick around and I'll show you the one habit that can save you a doctor visit, and it only takes a coin. We'll walk through how to track a sore for four weeks, what to note, and when to call a GP. By the end you'll know exactly what to do, no guesswork.

Why track four weeks

Cancer Research UK says any skin change that doesn't heal should prompt a GP visit, but they don't set a strict deadline. The four-week mark is just a practical point for a photo log, not an official rule. It gives a clear timeline for you and the doctor, helping avoid unnecessary worry.

How to run check

First, note the day you first saw the sore in your phone notes or a calendar. Then each week snap a picture using the same light, distance and angle, and place a coin next to the spot for scale. Finally, look for size, crust, bleeding, itching or any new spots and jot a short line each time.

Photo log tip

Create a dedicated folder on your phone, drop each dated picture in there, and label the file with the day number. When you finally see the GP, they can flip through the images in seconds, turning a vague story into a clear visual timeline.

Things that confuse

A few things can throw off your reading: constantly picking or pressing the scab can reopen it and reset the clock; areas like the foot or shin rub against shoes and may heal slower; regular sun on the same patch can change colour and edges; and conditions such as diabetes or smoking can delay healing, so a clinician’s eye is still needed.

Tracking period

Four weeks is the practical trigger we use for the check. If the sore is still open, bleeding, crusted or growing after that time, it’s a clear sign to book a GP. The timeline helps both you and the doctor see if it’s on track or needs attention.

When to call GP

Don’t wait for the four weeks if you notice any of these red flags: bleeding that won’t stop with gentle pressure, a sore that’s getting bigger fast, pain that’s getting worse, redness spreading outward, a fever, or a spot that heals and then comes back in the same spot. In an emergency, call your local number.

What to tell GP

When you finally see the GP, bring the start date, the photo folder and your one-line weekly notes. Tell them where the sore is, whether it’s bled, hurt, itched or crusted, and any similar past episodes. Mention any meds or long-term conditions like diabetes, because they affect healing. Hold off on new creams until the doctor examines it.

The one habit that saves a visit

And here’s the single habit that makes the whole process worth it: take a clear photo of the sore every week, always with a coin beside it for scale. That tiny reference lets you and your doctor see real change, and it can be the difference between waiting and getting help early.
