I had an baby got an epidural,since the epidural I been having severe lower back pain and numbness and tingling in my right. Now this what the doctor have told me since. Before I tell can tell you can you tell me the probem.One doctor told me I haveBack Pain with Sciatica, Hematuria and he went on im his notes I have MS and the MS is called Arthralgia and Muscle problem.Now another told me that Diagnostic were that he note Facet Arthrosis in the lower spine -L4-L5 and L5-SI and mild facet hypertrophy.But no significant disc bulge or protrusion is seen at any level. Disc space are well maintained. Now after my baby was born 2 month she  came down with Baterial Meningitis after I stop breastfeeding expain that to me.Because my back was hurting real bad they gave differnce medication, it might her the baby to stop breastfeeding. My question how did I go from good health to all these problem.I was execellence health nothing like maybe some back every now and then if I working hard.
