MedDRA: Breast pain, Burning sensation, Hypoaesthesia, Lymph node pain, Lymphadenopathy, Nausea, Pain, Paraesthesia, Sensitisation — Feeling: Fair

Free text: Very painful and swollen lymph node in armpit on same arm as injection. Started 3 days ago shortly after I submitted my last v safe check in but unable to edit last check in to reflect this. Pain and swelling progressively worse every day since, today being the worst day. Pain escalated to numbness and tingling down arm and radiating pain to breast. Making me feel nauseous. Numbessness and tingling and radiating pain lasted about 8hrs today but now resolves. Now left with just pain and swelling at lymph node, pain now more like yesterday. Separately, new sensitive area of left lower back in a very distinctive spot- about as large as my hand. Feels prickly similar to when you have a fever or a minor burn. This started as numbness and tingling in right arm was resolving.
