Yes, joint pain can be associated with PI. Because PI affects how the immune system functions, it can sometimes cause the immune system to mistakenly attack the body's own tissues — including the joints. Inflammatory arthritis is one of the more common autoimmune issues linked to PI. Studies suggest that around 3 in 100 people with CVID (a type of PI) develop inflammatory arthritis.

Joints that are commonly affected include:

- Fingers
- Toes
- Knees
- Ankles

Over time, this inflammation can worsen and limit how well the joints move. It's always worth bringing up any joint pain with your healthcare team, as they can help figure out the best way to manage it alongside your PI.
