Try getting ultra sound done on your tendonitis. Some chiropractic offices offer it. I have the WORST tendonitis in my elbow and have not been able to do triceps heavy in years. I have tried everything....fish oil, joint fuel, cissus, ice, celebrex, taking time off, etc. Ultra sounds help break up scar tissue. I go 3x per week and its been working wonders. Also, my chiro tapes up my elbow with this stuff called kinsio tape which basically helps to reduce any pulling on my tendon. I have finally been able to do skull crushers without any pain. I still am going somewhat light on my tricep exercises because I do not want to overdo it and end up right where I started.
