I am not a physician, but if I were you, I would be icing my elbow once a day for 15 minutes to keep the inflammation at bay. Acute tendonitis will force you to stop exercising and make you miserable everyday until your able to reduce the inflammation. Its your call, though.
I've developed acute tendonitis in both ankles from running in the sand while training as a beach lifeguard. Running became impossible and walking was tortuous. I've also had acute tendonitis in my right elbow and acute bursitis in my right shoulder at the same time. Quality of life was very bad until I started treaments. I took cortisone shots for the bursitis which worked quickly (though recieving the shots themselves are painful) but it took a couple of months for the tendonitis to subside, with agressive icing. I still get twinges of it. I don't like tendonitis!
