Detailed Answer:
Hello XXXXX, Welcome back to HCM,
I've gone through your query and understand your concern,

Since you haven't mentioned anything about fever/headache/runny nose/cough/body ache so I'm assuming they are not there (let me know if there's any)..

Now as per your description, it seems like viral influenza, which is mostly a self limiting condition but the change of voice can be due to laryngitis (?bacterial origin), is there any pain while swallowing foods/drinks ?

Good that you've started gargling with XXXXXXX warm salt water gargling..additionally start Betadine gargle (if you can't find Betadine, search for Povidone iodine gargle, it's widely available) three times daily for next 7 days.. also XXXXXXX warm salt water and gargle twice daily as an alternative fashion for next few days..

Tab PARCETAMOL 650mg (TYLENOL) two to three times daily after food for next 2-3 days for any fever and pain..

I suggest my patients to be on Tab AZITHROMYCIN 500mg Once daily (with or after food ) for next 10 days (it's strictly prescription drug, so please obtain it from the local physician)..

Steam inhalation three times daily (make sure to cover the head properly with a towel for 2-3 mins while doing this)..

Avoid cold drinks, dairy products, sour foods for the time being..

Make sure to remain well hydrated, drink plenty of water (~ 2.5 ltr per day) and XXXXXXX warm liquids (eg. herbal/green tea, soups, broths, porridge etc.).. avoid spicy foods and have simple home cooked meals for the time being..

With all these, you should be fine, however if at all observed any further worsening of the symptoms, recurrence/new onset fever, then I'd strongly suggest to get yourself clinically evaluated by any Internal medicine specialist or to any nearby healthcare facility..

Do let me know how you stay in the due course


Take Care
Kind Regards
