I had dry needling for lower back pain, numbness, tingling, and muscle cramping in my legs and feet in 2016. The procedure was painful, but worth it as the pain decreased by two numbers [1-10 scale], the muscle cramps stopped completely, and the numbness/tingling also decreased. This year the pain increased again by at least two numbers, numbness and tingling came back with a vengeance. Am in physical therapy again using dry needling hoping it will again help. Have a MRI scheduled tomorrow, so will see if any explanation why. My experience is dry needling works, but is painful to undergo. For me, the pain lasts about 24 hours after needling, then reduces to a lower level than prior to the needling. I have particular problems with my hip because one leg is shorter than the other.
