<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am 23 years and my period started on April 17 and April 21 and came again in twelve days which it started on May 2 and ended on May 6 and it was very painful and i had very bad back pains in my lower back which has never happened before.It came again on June 3 and ended on June 7 and this pain was even worse and even had headaches the pain lasted three days i took paracetamol for the pain but when they wore off the pain was unbearable. I also felt a dull stick on my left side by my lower stomach by my ovaries and I have this stinging in my breasts and they hurt sometimes when i touch them. I also have a three year old who stopped breast feeding around the middle of last year so i was wondering if that happens when breast milk is drying up. It it possible that i am pregnant and if so could something be wrong with the baby.  <response>: For severe back pain you can take some painkiller like ultracet-plus or zerodol-sp only when the pain is worse enough or disturbing your daily routine work along with some calcium supplements like shackled or toscal-gem once daily. Take some multivitamin like metilda-af or neurobian-plus once daily. Do some physiotherapy exercises after an expert opinion of physiotherapist. I will also advise you to sleep on a plain surface.
