What can i do for my achilles bursitis to heal faster ?

What caused it in the first place. Healing time will depend on what is going on. Discuss with your Dr who can give better estimate of healing time based on information you have given them.

I am wondering if this is a self diagnosis or a physician diagnosis? The reason for the question is that Achilles bursitis would be treated differently than Achilles tendinosis or partial Achilles tear. If you have not done so, see a physician who can give you an accurate diagnosis and an appropriate treatment plan.
