<s>[INST] Hi I have revived 2 steriod shot for back pain 2 weeks apart from each other. The second shot made me have menstural cycle 2days later and I m still going (3weeks). What should I do is this normal? And I m scheduled for a 3 epidural next week. IS this treatment dangerous to damage my ferterile state since I just turned 40? So far 40 has not been the new 20! [/INST] Hellowelcome to ChatDoctorwell epidural injections will only give u TEMPORARY RELIEF and once the effect of injections is over the pain will come again...for a long term relief you should visit a physiotherapist n ask him to teach you SPINAL EXERCISES FOR STRENGTHENING OF YOUR BACK MUSCLES n then perform those exercises on a regular basis at home...strong back muscles will prevent back spasms (cause of back pain) n that way you can make yourself free from back pain for long periods, also along with that start wearing LUMBAR BELT specially during Chat Doctor.  </s>
