If you were never treated for Scarlet fever you can get long term complications from it like Rheumatic fever or kidney problems. Also, fever, pneumonia, throat abscesses, ear infections and skin infections. Most people don't get the complications but it can happen and that is why they treat this with antibiotics early on. Maybe you can see an infectious disease doctor. Do you have any problems with your kidneys or heart? If not that hopefully you will be okay. You can get a throat culture to see if you carry it. But since you have symptoms you should probably see a specialist. Your symptoms could be caused by something else too.
