PET Sep 2022

Had Pet/CT done today, results Friday.  2 years 6 months on Ibrance, Letrozole and Denusomab every 6 months.  Suffering with arm pain so had pet with arms down instead of up, anyone with same arm problem and had scan position done differently?  If so did results differ?  I also had a molar extraction 7 weeks ago and I am concerned cavity will show metabolic uptake and mimic cancer.

I have had pet. scans with arms up and down, no difference with results. 
Fingers crossed for you x
