He said we can try switching to a 110 mm stem but I have to try and arch my back. Does the stem brand make a difference? Fsa vs race face vs etc?
Not really. Pain should not be ultimate determinant of proper fit, optimized comfort and speed should be. Of course pain is worse case scenario if fit is way off. My personal view is your fit is off. You may like it and not feel pain which is good but you join probably the 50%or more roadbikers with bad fit. Fit affects form as it were and not the other way around. A cramped cockpit for example promotes a hump back and bad posture for the simple reason that elongating the back and rotating the pelvis forward properly will make an already short cockpit unbearable. That is the predominant reason you see such bad posture on cramped cockpit bikes. By constrast on longer cockpit bikes you have room to stretch your back and ride with better posture.
I would say 80% of the advice coming out of local bike shops when it comes to fit is bogus. Further at least 50% of bike shops can't tune a bike properly. So what are bike shops good for? Selling bikes and equipment. There is no shortcut to getting good at anything. It generally takes more effort than people are willing to put in and why average is just that.
