Its most probable you are suffering from a Fixed pigmented drug erythema

to the particular drug. It results repeatedly after intake of the particular drug or drugs, each time occurring on the same spot.
Since, you started having the symptom ever sine you were taking zyloric, it is likely that you are sensitive to the active ingredient of zyloric which is allopurinol
. Hypersensitivity to the active ingredient of etody ( etoricoxib
The main arm of treatment is avoiding the drugs that are known to cause you the erythema and discuss with your doctor for possibility of prescribing some steroids
just to clear active ongoing reaction.
