Hi,I m a PE teacher,never had a back injury,but few days ago I felt sudden lower back pain,quite sharp,but bearable.Ever since,I fell constant dull pain in my back and I can t locate it exactly where is it.Also I have lots of gas,since the pain even more.I m having gas before the pain occured( a year and a half ago,after I gave birth) but I m wandering if all this is connected.I never had a gas problems before my pregnancy.I m 35 now and it was my first pregnancy.Thanks in advance for your reply.Liljana
