I received my first dose of astrazeneca vaccine on Saturday. Saturday night I was exhausted and fell asleep alot earlier than usual for me. I woke in the night countless times with excruciating back ache, shooting pain down my right leg, a headache that felt like it would blow my head off, sore muscles everywhere,skin felt like it had been sunburnt, very sore neck, I was not very mobile and felt like I was in a different body but Monday morning I woke up and felt absolutely fine. A little later in the afternoon I did develop a sore, red itchy lump just under the spot where the needle was inserted into my arm and again my legs felt like they had that stingy sore pain like you get from sunburn (only way I can describe it)
