OA in your toe, foot, or ankle can impair your mobility. In severe cases, you may become immobilized.
The hand and wrist include many small joints that work together to generate motion. When those joints are impaired, it can lead to pain and uncomfortable symptoms, as well as reduced or limited mobility in your hands.
Symptoms of hand OA include:
- dull or burning sensation in the hand

OA can cause pain and reduced mobility, but there are many treatments available. Work with your doctor to develop a treatment plan, and let them know if you have increased pain. OA is a degenerative disease, meaning it gets worse over time, so you may need to adjust your treatment plan as the condition progresses.
