Is left arm tingling more common in females, and why?

Left arm tingling can have several causes, and it might be experienced by both men and women. One condition that could lead to tingling is Thoracic Outlet Syndrome. This condition occurs when nerves or blood vessels between the collarbone and first rib are compressed. It is mentioned in the medical literature that Thoracic Outlet Syndrome might be more common in women.

Another possible cause of arm tingling is Subclavian Steal Syndrome. This happens when blood flow is rerouted away from the arm and can lead to symptoms like tingling. However, the literature does not specify if this condition is more common in females.

Lastly, de Quervain's tenosynovitis is a condition affecting the wrist and thumb, which might cause tingling in the hand or arm. Women who have just given child birth are especially prone to develop this condition. This is thought to be due, in part, to the repetitive tasks involved when caring for a baby.

In summary, while some conditions that cause left arm tingling may be more common in women, it can occur in anyone. If you experience ongoing tingling, it is important to consult a healthcare professional for a proper diagnosis.
