“I used to be a sidearm pitcher due to an injury a few years back that put alot of stress on my shoulder.”
Are you saying here you injured your arm throwing sidearm?
quote:
“My new pitching coach in college saw that I have quick arm speed and believes I should be throwing 3/4 instead to get a 90+ fastball that he thinks I should have”
You can throw 88-89 from down there? That sounds like nasty stuff, one of the greatest pitchers of all time (maybe #1) Walter Johnson threw from down there.

“After a month my shoulder feels horrible everyday and I have done everything”
Try getting your Humerus higher during drive, your coach will think it’s ¾.
quote:
“band exercised to jobes dumbell workouts”
Just as many before you that have injurious mechanics and now some of your talent and most your strength are designed to perform band exercises and dumbbell workouts. Try a “sport specific interval training program”

.” I'm not sure if this pain is due to using new muscles”
You are defiantly using different muscles that have not been given a chance to make the physiological adjustment, there is no way you can change mechanics and perform in competition immediately especially injurious mechanics.
quote:
“When I threw sidearm I was mainly 85-87 topping 88-89 without pain but had some control issues.”
This is where it gets confusing? If you had no pain how did the injury happen?
Were you side arm or ¾ here?

“What should I do?”
All over stress injuries to pitchers are mechanically oriented and fixed.
If you are going to continue with your northern movement in mechanics you better get it up even higher because 7/8 and down arm slots are where all of the traditional elbow and shoulder injuries are manifested from.
If you perform Humeral lag at initial forward force application (elbow trailing your shoulder line) you will have pain in the front and to the side (delts and R.cuff) Check your game or bullpen video!!?
To fix this problem you need to lock your Humerus in line with your chest at initial forward force application and turn the inside of your elbow up right at this point also then drive your elbow and shoulders together rotating 180 degrees instead of 90 to 100..
This will allow you to get into position to safely decelerate your arm straight out pronated more (rather than arm across your chest) which alleviates the other shoulder problems caused from deceleration where the pain will come at the upper back and shoulder.
You will find that all unnecessary stress then pain to the shoulder area will disappear.
If you are injured? The only way you’ll know is with an MRI, you will then need your Dr.’s release to continue. If you are just getting sore and are still playing and throwing you better change those mechanics that are causing your problems. If you shut it down nothing will be rectified and you will atrophy very quickly, then have to get back in shape before going all out again and then still have to change your mechanics anyway.
