The red eared slider might just be shedding its skin.
Or it might have a fungal infection.

pics? by: Anonymous
Can you post a pic? Is it a white bump like a pimple? If so, that is an abscess and you will need a vet to remove it. You'll also want to re-evaluate your husbandry.
If it's not a pimple like bump, it could be a burn if you have a heater. Or if you have more than one turtle, that is a common spot for bites. Anyway, please post a pic so we can give you some ideas.
