Having been diagnosed with both polymyalgia rheumatica and giant cell arteritis and put on high dose prednisolone I have been suffering from vertigo. This is often incapacitating in the mornings, when I can do nothing but sit with my eyes closed, but usually improves around lunch time and then carries on getting better, so that I am usually active in the afternoon and at my best (possibly able to walk without a walking aid) in the evening. Has anyone else experienced this?
