“Why do my fingers hurt when I try to make a fist?”

It may be due to a little tendonitis or even finger joint arthritis.

Hope it helps!

All of the joints in the body have articular cartilage that allows for the joints to do their thing - which is move. There are no blood vessels in the cartilage, so the only way the cartilage surfaces get their nutrients is from the joint fluid, which is only produced when we move the joints. Hence why you have trouble upon awaking in the morning. All joints get stiff and sometimes painful if they are not moved enough. The human body was designed for movement.

You may have a form of arthritis in your hands. You should see an orthopedic surgeon specializing in Hand surgery to get X-rays and an exam. You need to ask your parents if anyone in the family has a history of arthritis.

Could be multiple factors that could cause this. Please see a doctor for an evaluation.
