Sufferers often want to use a brace but it usually worsens the condition. We want to do almost anything to protect the injured limb and often favor it.

It's usually helpful to keep it warm but some people might prefer cool. Keep in mind that cold might stop the pain but for most of us the pain comes back worse.

Find a good doc. Your age and the fact it's recent are working very much in your favor to get a good outcome. Work hard and good luck.
