See your doctor.: There are many potential reasons for this type of pain, but it is impossible to sort out by just a text message. If this pain has persisted, then you need a visit to the doctor in order to take a complete history and do a physical exam. From there, the doctor can do possible tests, such as blood tests or x-rays, to help narrow down the cause of the problem. Good luck.
