Hi doctors, my son is 7 months 6 days now, his weight is 7.9, he recently had his flu injection, this 11th to be precise. I had cold. And he got it from me, he's managing but suddenly he's shaking his head side to side, I'm giving him sinerest and mucolite drops as given by pediatrician from last night... This head shake started after he had cold. What is that.. is it a ear infection. If it is, how to manage. I couldn't call my pediatrician as its midnight.. my stress level is through the roof. Please let me know.. Thank you doctors!
