I had a cortisone shot in my knee yesterday. Starting 3 hours later and continuing to today and now i look like i have bites all over my foot. They itch intensly and are oozing clear liquid. I took a benedryl. The itching has stopped. Allergic reaction to cortisone shot?
Hello, Welcome to Chat Doctor, Human body may be allergic to any substance which is foreign to the immunsystem. But the symptoms what you are having is may be due to some other infection rather than allergy to cortisone injection which you have taken for arthritis of knee. The rashes with oozing of the fluid may be due to fungal infection, or it may be an eczema or contact dermatitis. This is what I can suspect with the medical history. Thank you.
