Will having sex affect my arthritis?
Sex itself won’t make your arthritis worse. But because moving a joint affected by arthritis can be painful and because sex can be physically demanding, it may cause discomfort, especially if your hips or back are affected. You can try different positions which may be more comfortable for you and your partner.
Reactive arthritis can be triggered by sexually transmitted infections (STIs) such as chlamydia. If you’ve had this type of arthritis before, you should take special care to avoid getting such an infection (by using a condom, for example) because it could cause the arthritis to return.
