Welcome to HCM. I don't think your burning is related to the trauma you had 5 mths ago.
Since you have tired eyes too it could be due to Dry eyes
. Although lubricant eye drops will relieve you from burning sensation, it is wise to check for any refractive error
and evaluate for severity of dry eye and then use the medications.
Until you get an appointment cold
compresses for 10-15 mins twice a day should give a temporary relief .
Hope you feel better soon :). Take care.
