Write this in google "how to insert image in justanswer"
The first video will tell you how to upload an image.
As far as your question is concerned, there is no need for going to emergency room. This sounds like a viral pharyngitis
and that bump is probably a lymphatic band in throat. Examination can determine the exact cause but i can say this by confidence that in the absence of any high fever (higher than 101) and pain, there is no need to go to ER. You can just go on Monday.
Once you have inserted the image, i will respond. You can contact justanswer customer services for this also. I am an Ear, Nose and Throat specialist myself and reassure you not to worry.
