Epidural steroid injection symptoms and conditions

I am a registered nurse that works in a pain clinic. We give epidural Kenalog everyday for people with disc problems in their spines. I had been having pain in my left leg and buttock for about 10 months, got an MRI and had a lumbar epidural steroid injection for my disc protrusion. It worked beautifully, still pain free 5 weeks later. However, my period is on its 3rd week now! My GYN gave me Provera pills but it didn't help. My other problem is I have found a lump in my breast. My GYN thinks it is related to the steroids and will do a mammogram in 2 weeks if it hasn't gone away. Has anyone else had this happen after steroids? I am 38.

Epidural Steroid Injection of Kenalog. I asked about side effects and was assured it was a safe procedure. Within a few weeks I started suffering from pins and needles in hands and feet which progressed to severe burning pain over most of my body. I now live in constant pain (far worse than my original back pain) and have been told that I probably have Arachnoiditis as a direct result of Kenalog shot. Steroid injections in the back are at best only a quick fix and I would NEVER have had it had I known of the possible side effects. This injection has ruined my life.
