Thank you for your question.
I am Dr Saha, I shall try my best to help you.
I am sorry for your health condition.
If the headache continues to increase & gets intense, I would suggest to go to ER.
There are few other symptoms, which you can watch for.
Feeling of nausea, confusion, visual problems/blurred vision, weakness or convulsion, slurred speech, stiffness of neck, facial asymmetry, weakness of any limb etc, need to be looked for.
Respiratory difficulty or shallow breathing or fluid discharge from nose or ear are some of the symptoms which needs to be observed in case of trauma to head.
You can apply ice now.
This should not be applied directly.
Pl apply after wrapping it in a towel for 10-15 min., leaving in between for the temperature to return to normal.
You can take a tylenol.
I hope this information helps.
If there’s anything else I can do, please let me know.
If you are satisfied, please rate my answer as good or excellent.
