The eye condition you suffer from is most commonly seen with disorders like rheumatoid arthritis
and other connective tissue
disorders. The eye is not the primary source of inflammation but more a complication of the systemic disease. Hence, treatment for the same is in the form of eye drops but treatment of the root cause of the disease fixes the eye problem as well. The same is true for the headache. Your rheumatologist
will have to tackle the problem with oral medication and probably a maintenance treatment also to keep the condition in check. The episcleritis
will subside following that.
