Chest tightness with cold


So I went to my doc yesterday for cold/flu.    He put on Tamiflu thinking it might actually be flu.    My question is.. i have terrible chest tightness/wheezing and coughing up all kinds of stuff.    It's actually waking me up at night.

Should i be concerned about this or is there something i should just take over the counter, and if so, what would be those suggestions.


Thanks
