Thanks for writing your query.
After reading your post, it seems that your recent symptoms of running nose and body aches are due to viral infection.
Viral infection is usually associated with body ache.
You can take antihistamine like Cetrizine
10 mg once a day along with Paracetamol
500 mg for relief.
You should also apply antiseptic cream over the bruises.
If the problem persists, get yourself examined clinically.
I hope this is helpful to you.
