I started Saxenda on 12/25/2017. Yesterday 12/27/2017 I noticed about four 'pimples' on my chest that itch here and there. Today 12/28/2017 I noticed about 6 more in the same area. I generally do not break out ever. Wondering if this is because of the Saxenda and if so is it an allergic reaction or just my body getting used to the medicine? Any help would be appreciated!
