Hi! The closest reported symptoms to what you describe is myalgia. Muscles become painful for one of a few reasons such as auto immune disorder, compartment sydrome, or a reaction to the medication. Joint pain per se is not commonly reported. Is the pain associated with fluid swelling of the joints? Do your joints get hot? These are the sort of questions your physician will want to know.
The painful stiffening of joints happens in many conditions especially after rest, because fluid accumulates in the joint and is underbtension. Then movement 'pumps' fluid out of a swollen joint.
It is important for you to work this out as it may open up new lines of treatment for your condition.
