I've been getting tingling in my left thigh different times of the day don't know what's causing it. it happens periodically and it stops when i touch it or rub it.

Tingling : Tingling in the thigh could be caused by a number of problems depending on the exact pattern of the tingling and other related features. Probably the most common cause of tingling on the anterolateral thigh ("anterolateral" is a medical term meaning roughly "toward the outside of the front") is a condition called meralgia paresthetica. This is caused by a pinching of the lateral femoral cutaneous nerve. This nerve can get pinched in people, like me, who are a bit too generously-proportioned. It can also get pinched in other ways. Tingling in a band of skin, associated with a "bubbly" rash, could be shingles. Other things that might cause tingling in the thigh could include a process affecting the spinal cord or spinal nerve roots. Some of these things could be serious, so it is a good idea to see a doctor rather than try self-diagnosis.
