Thanks for choosing health care magic for posting your query.
I have gone through your question in detail and I can understand what you are going through. Upper respiratory infection
will take time to heal. The lymph node infection
is causing pain in your neck and the geberal inflamatory response in the body is responsible for body aches. You have been on antibiotics only for a few days and it will take more time. Take plenty of water, do warm saline gargles and steam inhalation, and take rest.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
In future if you wish to contact me directly, you can use the below mentioned link:
Wish you good health,
Dr. Srikanth Reddy M.D.
