Elbow Injury, Recovery Time

I have a question about my own personal rehabilitation. I took almost two months off from climbing in order to avoid causing further damage to my elbows. The pain I experienced was sudden and happened in mid-November during a day trip to my local crag. As soon as I felt the pain (which I later found out was medial epicondylitis) I stopped climbing, but the days following the incident showed me that this injury was not going to be short lived. I decided that I would stop climbing until I felt better. Within a few weeks the pain was entirely gone, but I decided not to rush back into climbing and opted instead to take another few weeks off. During those few weeks I did a regular workout program with small weights in order to rehab my elbow (supinators, reverse wrist curls, push ups, theraband exercises, and various stretches to promote blood flow). I have finally returned to climbing but have severely cut back on the intensity and frequency of my climbing sessions. So far, I have not experienced any pain whatsoever. My question is this: When do you think I can safely return to climbing at the same level of difficulty I was before my injury? Or, how do I best gauge my recovery? I don't want to make the mistake of rushing back to challenging climbs simply because my elbows feel good again. I want to make a smart, informed decision. Thank you for you help!
