11 day old newborn's stomach hurts so bad and is inconsolable.

My baby's stomach hurts her so bad. She tries so hard to poop, she kicks her hands and legs and she gets so red and hot. I can hear her little belly making all kinds of noise. She's gassy. I give her mylacon gas drops. I switched her gradually from similac to gerber soothe and she's been on it for probably 5 or 6 days. What can I do for her? She cries sooo much and is just inconsolable no matter what. She's changed, fed, swaddled, white noise, paci (which she won't take half the time), and being held and rocked/swayed, but still just cries because she's hurting. I feel soooooo awful seeing her in pain and not being able to calm her down or make her feel better.
