I notice you posted about the same symptoms in October. Have they continued since that time? Have you been checking your blood sugar levels and how are they?
Have you been to the doctor? If you haven't yet I really recommend that. The symptoms may not be related to diabetes so it is important that you get it checked out. The doctor may also be able to prescribe pain relief.
As you were advised in the previous thread we can't diagnose here but people will post about their own experiences.
I really hope you get some help as constant pain is very draining.
