Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain 
sore throat, body aches and nose bleeds can be due to viral 
throat infection  leading to loss of voice or Laryngitis..
It can also be due to causes like Sinusitis leading to 
post nasal drip..
I would suggest you to consult a General Physician and get evaluated and a thorough clinical evaluation and investigations like Blood tests, throat swab culture and 
Immunoglobulin G levels can help diagnosis and treatment can be planned accordingly..
In case of viral infection you need not to take antibiotics and can take symptomatic treatment to relieve symptoms..
You can take 
Acetaminophen or Ibuprofen to relieve body aches and sore throat..
Do warm saline gargles..
Suck throat lozenges to soothe the throat..
Sip on plenty of warm water and other warm fluids..
Do steam inhalations and use a humidifier in your room..
You should avoid spicy and chilled foods..
Do not strain your voice to try to speak aloud as it can further cause slow healing..
Take plenty of rest..
To stop nose bleeding pinch your nostrils gently for ten minutes and slightly bend your head forwards to avoid aspiration of blood..
Hope this information helps..
Thanks and regards.
Dr.Honey Nandwani Arora.
