Hello and thank you very much for your question. What you were most likely experiencing is an injection site reaction. D’s can sometimes go away within 24 to 48 hours for these can stay for months. Sometimes these reactions can also be painful and elicit other immune responses such as difficulty breathing, etc. My best advice is to contact the veterinary clinic that administered the injections and tell them what you are experiencing. What most likely will happen is that they may want to re-examine your animal and possibly give you some topical or oral or injectable medication to offset the inflammation. Generally, these appointments do not cost anything and be makers of the vaccine take care of the costs associated. But this all depends on the veterinarian and the clinic involved. So I Urge you to call the veterinary clinic and schedule an appointment as soon as possible to get this lump checked out. We really appreciate you using our service. I hope I have helped.
