Tendinitis can reduce in pain by itself over time, but it may heal poorly and be weakened. This could lead to chronic injury at the same tendon over and over. Get some treatment for it or, at the very least, look up eccentric exercises and start doing them for the tendon involved. Eccentrics are shown to help correct tendinitis that are chronic (more than 3 months).
