Colic baby please help

One of my twins has colic, I have tried almost everything from gas drops , massaging stomach, bicycling legs & gripe water and I don't know what else to turn to. If anyone with any suggestions please tell me it would help a lot . Im tired of seeing my poor baby suffer and hardly get any sleep due to always waking up to push and grunt, also when he wakes up he starts moving his arms nonstop with his fist balled up and kicking his legs around and I just feel useless because I cant help... along with colic effecting my baby it's taking a toll on me because I'm always so cautious and I just literally don't get any sleep and I've never been so drained in my life so if anyone has anything to help please tell me ...
