I just finished a 40-day ChatDoctor diet - consisted of a shot a day mixed with B12 and staying on a 500-calorie diet.  On the night of my last shot, I got hives/itching on bottom of both legs.  The next day it moved to my arms.  Now it is on my chest and neck.  Is this from the ChatDoctor?
Hello, It could be an allergic reaction to Chat Doctor. I would recommend you to take antihistamines like tablet cetirizine 10 mg twice daily for 5-7 days. This should resolve it. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
