I was recently diagnosed with Behçets roughly 2 months ago. I'm taking 10mg of Predisolone which has stopped my mouth ulcers for the last 4weeks thank god!! but I also suffer with styes as well which did stop coming but have come up the last week I think I may possibly have a mild flare up. The steroids haven't helped with my pain over my body mainly my back what so ever but since I've been taking them I've had agonising pain in my knee and my calf . Can anyone advise me how long it will take to help my pain or if it will help with pain also if the pain in my leg is because of the steroids?
