Hi there,
Part of the symptoms of an influenza virus is
runny nose, sore throat, achy body, general malaise. Virus normally stays active for 14days.
Up your intake on vitamin C and spray your throat with antibacterial throat spray.
If you are completely over your cold and still feel that you have a lump in your throat that does not want to go away, then you can seek the help of an ENT Specialist to check out your throat/sinuses, etc.
All the best and let us know how you are doing.
