I'm having serious problems in both arms. Left arm is a probable partial distal tendon tear and right arm is tennis elbow or some crap. Now most lifts are fine. I wrap the areas and lift cautiously. I can lift heavy except in one area. One arm dumbbell curls. Curious if anyone has had any issues like this and if they still can get good gains. Curl bar, straight bar curls, machine curls I can go decent, but that pump I used to get from concentration curls and hammer curls is lacking. It may be something I have to deal with forever. My left bicep is noticeably elongated and doesn't have that nice head like my right. I'm not a competitor, but it bothers me just the same.
