Has anyone experienced left arm tingling and numbness with RA, and what was the diagnosis?
Yes, tingling and numbness are experiences that many people with RA share. These sensations can occur for a couple of different reasons.
Peripheral Neuropathy
This is one of the most common causes. Studies show that 10 to 20 percent of people with RA develop peripheral neuropathy, though some research suggests it could affect as many as 50 to 85 percent of people with RA.
Peripheral neuropathy happens when the nerves outside your brain and spinal cord become damaged. This damage prevents nerves from properly sending signals to your muscles and skin.
Symptoms can include:
* Tingling or pins-and-needles sensations
* Numbness
* Muscle weakness
* Increased sensitivity to touch
* Painful or unusual sensations
In people with RA, these symptoms typically appear symmetrically on both sides of the body and can affect the upper or lower limbs.
A myRAteam member shared: "I have no feeling in my ring finger and pinky on both hands. It's strange to not have feeling in them. Makes them seem weaker than they are." Medication Side Effects
Some RA medications, particularly methotrexate, can also cause tingling and numbness. If you're taking methotrexate and develop these symptoms, it's important to notify your healthcare provider right away, as these can be signs of side effects that may need prompt treatment.
What You Should Do
If you're experiencing tingling and numbness in your left arm, talk to your doctor. They can determine whether it's related to RA itself, peripheral neuropathy, medication side effects, or another cause. They may prescribe medications to help relieve symptoms or recommend therapies like physical therapy or assistive devices.
Because these symptoms can overlap with other RA symptoms, proper evaluation is important to get the right diagnosis and treatment.
