5. Changes in Feeling
Any changes in the way your moles appear are always a sign that you should report to your doctor, but you should also take note of any changes in how the moles feel even if there’s no change in their outward appearance.
Generally speaking, moles aren’t supposed to hurt – and when they suddenly do, you should try and find the cause behind it. Sometimes it might be clothing that hooked on the mole and caused some discomfort, which will usually make it appear irritated and red – but if this persists and it’s not a simple issue of the mole getting irritated, then you have more cause for concern and should make an appointment with your doctor.
Changes in feeling can go either way, and you might find that the mole becomes either less or more sensitive than before. In either case, you should make an appointment with your doctor for this.
