Your husband is very important to take care of but if you don't take care of yourself how are you going to care for him? Is there someone who can take him to an appointment if it interferes with your appointments? You need to see someone that can help you deal with your pain and determine whether it is diabetes caused or not. The longer you wait – the longer your pain exists. Also, if you need to start taking meds for your diabetes please do so. Your health is more important than fighting your blood levels all the time. Prayers to you as you go through your struggles.
