Hi.
Noted your history of having cold, blowing of nose followed by popping of ears,
motion sickness, eyes twitching which settled but the headache and nausea continued.
The commonest causes I can think about are as follows:
The blowing of nose cause the Eustachian tubes to open up and push air or fluid inside the middles ear, the pressure increases causes the symptoms that you have mentioned.
I would advise you the following in such a situation:
Consult your Doctor, preferably an ENT Surgeon for clinical evaluation, examination, ENT
Endoscopy to know the state of nose and tympanic membranes.
This will allow a proper diagnosis and get your treated as per the findings.
This can be in the form of Nasal decongestant drops, oral antihistamine,
steroids and anti-inflammatory.
Do not blose nose again.
Take a long term treatment of 3 weeks as such disease takes time to go back to normal.
Symptomatic treatment with a PPI like
Omeprazole and
Domperidone for motion sickness may be added on.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, General Surgeon
