The biggest thing with inflammation injuries like bursitis and tendonitis is to rest, massage, and ice them. These will significantly speed up recovery.
Like tendonitis, it's very easy to aggravate the condition again so you need to work back into it VERY slowly, especially since your condition is chronic. And by very slowly we mean very VERY slowly. You shouldn't be anywhere near the same level of activity for at least a month or two to be safe. Start with like 10% and build on that every 2-3 workouts.
I'm no doc or PT + this is the Internet so take it with a grain of salt.
