Welcome to HCM.
I think you must have been suffering from Upper respiratory tract
infection along with conjunctivitis
Good to hear you are getting better.
In any infection as a part of defensive mechanism ,the lymph
nodes in our body enlarges and this becomes painful on touch and with movement of the cheek in your case. Once your infection comes down,then you will get relieved of it . You can take an additional dose of oral anti inflammatory
Drug for relief .
So wait for a period of a week to be totally off from your symptoms and add a Lubricant eyedrops for soothing your eyes.
Hope this helps. Take care.
