How do I distinguish between strep throat infection from other sore throats? (photo)

Thank you for your question. I would need to understand your symptom better as the throat is a symmetrical structure and moves symmetrically (right and left sides) on swallowing. Since you mentioned that you have a "flu" a few weeks back and it appears to be coming back, there is a possibility that you may be feeling the mucous from the back of your nose flowing down the back of your throat (maybe more on the right side), hence giving you the feeling that your throat is "moving to the right".

It is important to know the cause of your sore throat so that the correct management strategies can be recommended to you. Amongst the common causes of frequent sore throat include: Pharyngitis - This is usually due to a viral infection of the throat (most commonly the common cold, influenza and mononucleosis). Your body can usually fight off the infection and to speed up your recovery, plenty of hydration, rest and sleep will help. Pain relievers, gargles and lozenges will also help keep your sore throat under control.
