Just come back from holiday to a letter from the hospital regarding an appointment with a rheumy 2 weeks ago. It was a locum Consultant Rheumatologist that I saw. He says in the letter that the reason I am tired and lightheaded is steroid induced myopathy. He is recommending I am prescribed Methotrexate/Lefthunomide I don't know anything about that stuff. All I know is it doesn't sound very good.Anybody help?
