In the afternoon doc. I want to ask. My father is 53 years old. In the last 5 months, one of his fingers has become stiff after waking up. And after being used for activities, his fingers are no longer stiff. It has been 2 times treatment, and the last one was given drugs “METHYLPREDNISOLONE” and “NATRIUM DIKLOFENAK” by the doctor. What I want to ask, is this disease dangerous or not? And can it be cured? And is there a better drug than that drug. That’s all, thanks doc.
