Arm pain, hip pain, bone scan, oh my!

Having right arm pain that feels like a bad tetanus shot on the outer side. Can’t hardly lift my heavy purse without pain. Can’t reach my arm out to the side without pain and it feeling heavy. Right hip hurts when I get out of bed and lasts until I take Tylenol or Advil usually which I’m eating like skittles. Every day. This has been going on for a few weeks. I had a clean PET scan so I don’t know what a bone scan will show but my doctor likes to cross his T’s and for his I’s. And for that I’m grateful.
