I injuried my back on the job and have had severe back pain with shooting pains to both of my legs and feet. I had physical therapy which made it worst! finally they did a MRI after 5 months post injury! Finally they referred me to a pain management dr, who recommend an epidural steroid injection. I had first one in Feb. it really helped! I am  menopausal but have had 2  brown spotting like peroids it last like 2 weeks and went away. I had a 2nd injection April and now i am spotting again like a browish peroid. I had not had a peroid in over 4 years. This ESI has help me tremendously but like many others I have gained like 10+ pounds and have a peroid again. I am bless to get relief from all the shooting pain, but my back still hurts just not as bad. I have pain everyday and I take meds for the pain. Glad to hear that others are having similar issues. I thought I was having female problems, I went to my PCP had a pap smear and it was normal.....
