Hi,
Noted your history of
severe back pain after an attack of
sinus infection, even slight coughing is causing more pain.
The causes I can think about are as follows:
The sinus infection can spread to the body through blood and cause overall
myalgia.
Back being composed of muscles that are most used get affected first as that of neck and low back and calves in particular.
Hence you need the following:
Consult your Doctor for clinical evaluation, examination and investigations of blood and CT scan of
sinuses to know the exact extent of infection or so.
Blood culture to see for the spread and get culture and sensitivity to know the causative organisms so that proper treatment with antibiotic, anti-inflammatory can be started along with symptomatic treatment.
This will allow the cure.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, ENT and General Surgeon
