How to ease arthritis with yoga
Talk to your doctor.
Before you begin any yoga practice, whether you're joining a class or just learning a few easy poses to do at home, get your doctor's opinion. Your doctor may have certain restrictions they want you to observe, at least at first.
If your doctor has specific restrictions or recommendations, get them in writing so you won't forget them and can show them to your yoga instructor if you join a class. Tell your doctor if you have any other chronic health conditions or concerns that they don't know about.
