RA sometimes affects the small nerves in your hands or feet. They might feel numb or like you’re being stuck with pins and needles.
If these tiny blood vessels in your hands or feet shut down, your fingers or toes may feel cold or numb. They could even change color when it’s cold outside and look white, red, or blue.
If your hands or feet are so numb that they drop or go limp when you try to raise them, see your doctor right away.
Numbness and tingling are side effects of biologics, too.
