Hi.
Noted the history about an Opera Singer, certain discomfort on throat muscles since 1 year, after high note down, consulted Doctors and got medicines for muscles but no relief, no vocal problems, done vocal exercises,
acupuncture.
This looks to be abuse of the muscles that participate in production and modulation of sound.
It is great to know the vocal cords are normal.
Hence I would advise you the following:
First of all it is most important to have ''voice rest.'' This means no speaking, no singing at all.
The basic of any muscular strain is rest and this is possible only by voice rest.
To have proper examination of the muscles and bones, cartilages.
Anti-inflammatory medicines.
Oral
steroids if there is no
diabetes.
All these measures should help you out for muscle relaxation.
Consult an ENT Surgeon and speech therapist before starting speaking and once the speaking is normal then start singing after go ahead by your Specialist.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, ENT & General Surgeon
