I received a 10 mg Kenalog shot on 06/15/05 and had a period that lasted 1 week( heavy flow) 11 days after recieving the shot. This year on 6/02 I had another 10mg shot given and experienced severe hip pain for a couple of days, and now both hips hurt horribly all the time, and I started my period last Saturday and have been bleeding for a week now. I am 4 years post menopause. Last year I had numerous tests, ultrasounds, and a biopsy done to try to figure out what made me bleed. I am 54 years old and I will never have another Kenalog shot for hayfever/ allergies again.
