Pain in right side

Okay I've had this pain since last Sunday so for about a week now. It's only in my right side. I went to the doctor about it on Tuesday and he said it was UTI. I thought okay answers! Well, I've been taking the medicine just like they said and the pain still hasn't gone away. It's only got worse to the point I wake up from the pain during the night. I've started sleeping with a pillow between my legs last night to see if that helps. If it doesn't I don't know what to do or what it could be. Anyone else have this problem? If I lay too long in any position it starts hurting and if I move too much it starts hurting. I can't win! Please help me guys... :/
