Hello. Has anyone had the Mirena inserted and experienced sciatica? I started getting sciatica 2 days after my Mirena was inserted last month. It disappeared a month ago but it's now back again - lower back pain and numb bum. I have not experienced these symptoms prior to having the Mirena inserted. My mum asked me if it could be linked. I dismissed it as I thought it didn't add up but now I'm wondering! So has anyone experienced sciatica with Mirena?
