My elbow tendons have been really painful from some work I did last fall through March. It didn't bother me while was initially doing the movements and I decided this is making me stronger. But much to my surprise I am human and later it began to feel like someone shot me in elbow with a .22. The pain comes and goes, very painful on curls and snatch.
I read doing slow eccentric movements / let downs in curls would help strengthen ligaments. I rebooted those lifts for a second time beginning a week ago. I will let you know if it works for me. There's also some kind of strap you put on and tighten from time to time but I haven't found it.
Taking 1000-1500 mg of vitamin c and a powder called Joint Juice - I put in green tea. I'm older than you so it may take longer to heal, but I don't have the extreme pain that I did months ago.
