Shot is given incorrectly (in the muscle) can cause bruise. I found this source from Cincinnati Allergies & Asthma Center website. I am experiencing the same problem at my clinic, so I am looking a different clinic where my allergy shots can be given correctly. Hope this help
Hi,
You need to get a blood work done and also talk to your allergy specialist about this.
You should ask about whether taking antihistamine medications would help after the shots to help reduce the bruising. Apply calamine lotion at the bruise areas.
Let us know if you have any doubts and also about how you are doing.
Hope this helps.
Regards.
Hi,
It would be best to consult with your allergist, or the person administering the injections, to advise you as to what you can do, or what they need to do. Sorry, couldn't be more help.
