I have a mare due in roughly two weeks. I just went out to give her two shots (Rhino & Potomac Horse Fever -- Im pretty sure), she gets two more in two weeks (ya im two weeks late -- I really hope that doesnt affect anything, or Ill just quit with these two). Anywho, RIGHT after I gave her the PHF I noticed hives on only that side of the neck (left). Im sure they must have been there before the shot, cause theres no way they came that fast, but it was dark so I dont know for sure. Theyre not air bubbles or anything, its all over the neck, not visible, but I can feel them. Anywho, is should I be concerned? Also, if you have any tips or suggestions on my giving these two shots so late, please let me know. Thanks!
