sever abdomial pain now on both sides

so iv been having sever pains on and off for about 3 months now in the upper right of my abdomen, first i went to my gp and he gave me tablets to reduce stomach acid, and they did nothing, i then had another episode of the severe pain and went to the local hospital but they told me to go to my gp again, then i was told to just manage the pain with paracetamol. since this iv been to a&e and the dr told me it sounds like gallstones from were the pain is coming from and i need to get refereed to a scan from my gf (i have an appointment on Thursday), but the last 3 days iv been waking up in the night with pain in both sides just above my hips (id guess where my kidneys are), its not like the pain iv been getting in my abdomen but very discomforting. iv not just round blood in my stool (in it, not around it, iv had an anal fissure before and its not like that) and im really worried. would just like an option because my gp isnt helping alot and the pains are getting worse. any ideas ??
