You told that the white skin lesions have been present over your body for 16 years. I hope the lesions are asymptomatic.
It may be a chance factor that these lesions appeared just after getting the injection.
You may be suffering from vitiligo
. If the lesions are progressing rapidly, then you need quick consultation with a dermatologist
. Because the regression of vitiligo lesions is a little bit unpredictable, but the progression can definitely be prevented by initiation of treatment.
