I Had Same Symptoms As Some Of Them Who Ask

I had same symptoms as some of them who ask u questions here. Tetanus jab given 1 n a half day ago n I started having pain at my neck (particular area nearer to ear) n both shoulders. Under my underarm gets irritating ache n also injected area was pain throughout the night yesterday while sleeping. Pls advise.
They r all happening on left side of body, co-incidentally I got scalded on my left leg before the jab n got injected on my left arm.
