Hello all! I had an ultrasound today to add to the lists of scans I have been having for investigation. Kinda bizarre but the scan was ordered of my left side, however, after scanning the side the sonographer said he was going to do the right side for comparison. I have never experienced that before regarding any scan so just wondering if that is common or not.

from what I could see from the scan as someone with no medical skills it didn't look like anything sinister but it does just look like a greyscale mess to me! 
 

Thanks in advance!
