Around the time of thanksgiving I went to a doctor
Hello, I'm Dr. Branch, thanks for using Ask a Doctor. If you did in fact have strep throat, the risk of rheumatic fever in general is low, fewer than 0.3%, and it mostly occurs in teenagers. I would look for any symptoms of rheumatic fever, and if you have any of them, get evaluated, otherwise there wouldn't be any need to worry. These include joint pain, chest pain or shortness of breath, neurological disorder causing unintentional muscle movements, a rash, nodules under your skin, especially around the elbows, or fever. If you have any of these, I would recommend you see your doctor to get an EKG and may a heart ultrasound to make sure there were no signs of rheumatic fever affecting your heart, which would be the most concerning complication of rheumatic fever but again would be very rare in your case.
I hope that helps, let me know if you have any other questions and I'd be glad to discuss it further with you.
