So i went to my local Wallgreens looking for some ultrasound gel. I asked my pharmacist if he had any thoughts or suggestions on the subject. He told me that they do not carry the gel for ultrasound however he suggested a substitute. He told me KY Jelly could do the job too. So I purchased some KY and will commence to rubbing it along my head. I use mine along my temporal lobe to assist with inflammation in this part of my brain. I also told my husband to keep his mind out of the gutter if he wants to know why I am rubbing KY Jelly all over my head.
