Common signs
- Joint pain and swelling — often traveling from one joint to another (migratory arthritis)

🍽️ Eating to help
Food is one of the gentlest medicines — small, steady changes help most.
Favor these
- Fresh fruit and vegetable juices during the acute phase
- Light plant-based meals once solids are appropriate
- Bioflavonoid-rich foods: berries, citrus, dark leafy greens, grapes
- Plenty of water
Go easy on
- Caffeine (coffee, tea, cola)
- Fried and processed foods
- Salt and heavily salty snacks
- Added sugar
A clean, plant-based diet reduces inflammatory load and supports recovery alongside proper medical treatment.
⚖️ Good to know
- Rheumatic fever is a medical emergency — do not rely on home care alone.
- Untreated rheumatic fever can cause permanent heart valve damage leading to long-term heart disease.
- Complete all prescribed antibiotics even when feeling better — the strep must be fully cleared.
- Recurrence is common: each new strep infection can trigger another episode, which is why long-term antibiotic prevention is prescribed.
- Sydenham's chorea (involuntary movements) can appear weeks to months after the initial illness and also needs medical management.
