You’re a bit ancient for rheumatic fever, but here are the symptoms.
Rheumatic fever symptoms may vary. Some people may have numerous symptoms, while others experience only a few. The symptoms may also change during the course of the disease. The commencement of rheumatic fever usually occurs about two to four weeks after a strep throat infection.

The signs and symptoms — which result from inflammation in the heart, joints, skin or central nervous system — may include:

■Fever
■Painful and tender joints — most regularly the ankles, knees, elbows or wrists; less regularly the shoulders, hips, hands and feet
■Pain in one joint that migrates to another joint
■Red, hot or swollen joints
■Small, painless nodules beneath the skin
■Chest pain
■Sensation of rapid, fluttering or pounding heartbeats (palpitations)
■Fatigue
■Shortness of breath
■Flat or slightly raised, painless rash with a ragged edge (erythema marginatum)
■Jerky, uncontrollable body schedule (Sydenham chorea or St. Vitus’ dance) — most regularly in the hands, feet and face; less regularly in the arms and legs
■Outbursts of unusual behavior, such as crying or inappropriate laughing, that accompanies Sydenham chorea

If you have a symptom match, it’s worth a trip to the doctor. If not it might just be remnants of the strept throat and German measles..that’s a tough combination.

BTW, I had Rheumatic Fever as a child and didn’t have any lasting problems from it. The tip off was aching in my ankles joints following strept. Excellent luck.
