Hi,
Noted your history of
severe sneezing and pain in chest and back on sneezing, worried.
Sneezing of this extent indicates an allergic cause .
The pain in chest and back is due to activation of secondary respiratory muscles during hard sneezing as a part of body mechanism.
The
costochondritis also can cause such pains as the muscles originate from ribs.
Hence I would advise you the following:
Control of sneezing.
Antihistamine.
Steroid
nasal spray.
Oral
steroids if required, needs a valid prescription of your Doctor.
Opinion and examination by an ENT Surgeon for further evaluation, investigations like
Endoscopy, CT scan of nose and sinuses to see the secondary effects of allergy.
And further management as per the findings.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, General and ENT Surgeon
