Anaphylaxis help needed Facial swelling, tight throat

Patient: I’m anaphylactic. My last reaction was a slow but violent onset. I came into contact with allergen day one, rash day two, cough on morning day three and late day three afternoon i started swelling up and had a blocked throat and was given adrenaline after i took myself to the doctor. Lastnight i slept in my bed where my cat (i believe to be my allergen) had slept during the day, and now nearly 24 hours later im forming a rash on my chin/nose/lips and itchy hands. I dont know when i should give myself adrenaline or take myself to hospital. My throat is slightly tight.

Symptoms: Anaphylaxis, tight throat, facial rash
