Allergic Reaction

So the progesterone in oil shots--the oil is sesame oil. I get getting 34 days in sesame oil injections has made me a little sensitive. I have been itchy all over, legs, arms, back, stomach, but especially where I get the shots in my hind quarters. So I showed the doctor today and he said, "Oooh that looks bad." Welts and bumps all over. Anyway, now I need to take a Benadryl one hour before the shot. After tonight, only 35 more to go.
