I had a tendonitis in my shoulder. I went to physiotherapy and was not be able to work for 7 months ( I had an Acro Balancing act ) until I went to another physio. He prescribed me a thee spoons of vodka or another spirit on a sheet ( or cut it in half ) of kitchen paper on the tendon then wrap it with cling film during the night.
Every night for a week until the inflammation is gone. Continue another week replacing the spirit with plain water. I was back to working in the circus after that.
