I’m 63. I’ve had bleeding following back injections going back to 2018. I went to my gynecologist and never thought to mention the back injections the month before. He put me through tests, sonograms, biopsies, and I was put on progesterone for 6 months. Eventually in 2019 my gynecologist made the connection when I told him I had had back injections 2 weeks prior. However it never happened when I had knee injections. I assumed it had something to do with the back injections being done at a surgery center and possibly the injection site being closer to my uterus. Well recently I had a shoulder injection and I started bleeding 2 weeks following, and it was worse and lasted 2 weeks, unlike any previous times where it was mostly spotting for 5-6 days. I just found out that the doctor used Kenalog vs the Depo-Medrol he used in my knee. I wonder if Kenalog is the one to avoid. I will mention it to my gynecologist and see what he says.
