Icing arm: Area all around bump is Cold. Bump itself still feels HOTTTTT. Itchiness has not left. Reddish bump has changed to a dark pink color. Seeing it slightly brownish too. Around the bump there is a ring that has formed. Light pink in color it has permeated day by day. Still icing arm. Avoiding the sun so as not to irritate arm.  Day 13 AM Bump still there. Pinkish hue. Slight irritation..not as intense. Concerned about the ring around the arm that keeps permeating. Resolved to show up at the Rx so they could see for themselves what I have.  Day 13 PM Arrived at Rx. Attempted to show my left arm area to pharmacist that gave injection but it nearly cleared by the afternoon and by the time I got there?  Pinkish hue was there along with the ring but it was almost clear! I showed pictures as proof of my concern. Was given assurance that I am okay. (Concerned because every person I spoke with that got the vaccine never experienced what I did with Moderna), Was given Cortizone (with Aloe) to purchase to help with itchiness that remains. Was instructed  for my 2nd Dose to stay longer for them to check for any allergic reactions.  Day 14-19 Experienced Periodic itchiness. Applying anti-itch cream was enough. Iced only on Day 14 just in case any fever remained on arm that I could not feel. Arm immediately felt cold from icing. Concluded icing was no longer necessary. No bump on arm. Large Brownish spot has remained where the pinkish bump used to be. Resembles a slight bruise. Darker than  arm color. Hopefully original look of arm will return.
