The only caution I would give you is to watch closely for the symptoms of Giant Cell Arteritis. PMR by itself is not life threatening, but GCA is another story.

Excerpt from article below - "If you have polymyalgia rheumatica, you are at a higher risk of getting a condition called giant cell arteritis (GCA). This involves inflammation of the blood vessels called arteries. This needs urgent treatment as there's a risk of permanent loss of your eyesight or having a stroke with giant cell arteritis."
