Tendonitis / Tennis Elbow from lifting - advice?

Backstory: I was going to the gym and doing a PPL program 3-4x per week all year and decided to ramp it up to 6x week on 10/1. As of this past weekend, both elbows are killing me. The pain is on the outside part of the arm. I had to take the whole week off from the gym,. Researching it seems like it is tennis elbow/lifters elbow/tendonitis due to overwork. I ordered some elbow compression sleeves from Amazon and they don't seem to be helping a whole lot. Have any of you experienced this? How long did it take to heal? Any tips or tricks to help accelerate that? Did you just not lift weights when it healed?
