Swollen lips

My 20year old daughter had her first Covid-19 vacation on Monday 6th Dec, about 6hrs after administering this she experienced sore lips, headaches, nausea and flu like symptoms, the following morning her lips, mouth and throat swollen with bruising on her tongue. She could not swallow and looked to be having an allergic reaction. I took her in the chch hospital, they took blood test and checked her blood pressure which was higher than normal. They said she had a virus and gave her liquid Panadol and sent her home. She was very sick for about 10days and spent many in bed without eating. She also had night sweats and still not fully recovered.
