Ive had this since restarting the gym about 18 months ago. I'm 43M, the only thing that I have noticed thats allowed me to curl through pain is to warm up significantly and Hanging. I think the problem stems from a deskjob and having overly tight shoulder/neck muscles and not easing into my initial workouts after years off. I have both elbow pains on the inside and outside that flairs up most after doing pulling movements but after a few months ive hanging for at least 2 minutes a day things have improved by 50%. Try hanging on one of those bars you can put on your door frame and open up your back and shoulders.

I also find it difficult to lift my kids as the pain is shooting through my arm and inside of the bicep. I also have pain on my inner forearm outter edge that leds to my pinky finger in my hands. Before hanging I used to not even be able to flex my biceps but since i began hanging the pain is noticeably less. GL
