It was elbow pain and my doctor always told me it was tendonitis and just rest it with ice and ibuprofen. The last two weeks my elbow hurt any time I used it. That day I literally could not swing a hammer with my left arm. The elbow only hurt when I moved my arm so I went ahead with my deadlift workout that day and skipped my assistance work. The elbow did not hurt at all doing deadlifts so I decided to do some heavy singles as assistance. I did a set each of 380 and 390 with no pain using the alternate grip. 400 pounds was too much for the tendon it appears. The surgeon was surprised with my progress too. He was going to use the endobutton technique for repair. That is when they drill a hole in the forearm and pull the tendon through it and suture a button to the end of the tendon. My tendon was so degenerated that he had to trim nearly half an inch off of it to reach good tendon so that procedure would not work. He ended up doing the double anchor method where he screwed two anchors into the forearm and sutured each side of the tendon to one of the anchors. I had nearly full ROM at week 2. I was just a bit short when twisting the forearm. He told me at week 11 I was good to go just take it slow. I still have limitations. At work yesterday I tried to hold my tool bag in my right hand and one arm it left handed down a straight up and down roof access ladder. halfway down I had to drop my tool bag so I could grab the ladder with my right hand as my left bicep started hurting.
