Have you felt this before? Or has anything happened recently to u? It may just be flu or a common cold. I'd say just pop yourslef down to the doctors, and i'm sure they'll fix you up!

Hope you get better

Hii
i think you are probably down with flu
take a break from office and rest at home for a few days
drink plenty of fluids and also hot soups like garlic soup
you can consult your doctor who will give you medicine like tamiflu which is really good for treatment of flu
