Have you ever treated bursitis?

I was surprised to see my ankle after morning exercise around July 20th.

The area around my left ankle is extremely swollen. When I went to the hospital, they said it was bursitis.

There is no pain, but the swelling and fluid in the water pouch are not draining well.

The photo shows the condition after nearly forty days of medication and acupuncture treatments.

I feel so frustrated and bored being stuck at home unable to exercise.

Is there anyone with experience or knowledge of good treatment methods?
