Most drugs only block the pain signal, they are not a cure. The sports medicine mantra, rice, - rest ice compression, and elevation. If you are squeezing your bow hard, it can aggravate the tendons. This is in your drawing arm, try to keep your elbow lower and try to draw straight back no more than a few inches. Pick up most of the draw when you are bringing up your bow. I have had the tendon problems in both arms numerous times. The worst was with a light weight target bow, another time it was from putting up ceiling sheet rock, another was from weight training, and once in the right arm from practicing a straight draw with a 96 pound bow in a tree wedge, trying to keep warm. I was freezing, under dressed and the only way I could shoot from the perch was to poke the bow out flat and then draw it straight back. I shot an arrow through a deer that year with a 35 pound bow on the ground, while I was making my morning tea over a stick fire. Careful, this can last a long time. If your joint is twisted it will reoccur more often. A chiropractor can help if that is the case, but the "rice" will still be needed.
