Brief Answer:
it's a bruise

Detailed Answer:
Dear member,

Thanks for writing.

The red mark which was present earlier is a bruise. A mild bruise occurs due to minor trauma like nudging when small blood vessels rupture under skin.

Over few days it will change colour to yellow or yellowish green before fading away.

I don't think it's a cause for concern.

Please consider further treatment with a doctor if there is a mass felt or the bruise doesn't resolve.

Thanks
Dr Bhagyashree
