Hello you sound just like me with having cold after cold, mine started just after i had my second baby 5 months ago I have just had cold after cough after sinus congestion after cold it only seems to go for a week or two then i feel like i am getting another cold, it is just going round our house all the time we can't seem to shake it off, i had some antibiotis a few weeks ago for a cough as it was making my chest ache and coughing up coloured phlem(sorry) they worked but yesterday and today felt like the cough is back i am so sick of it, it is starting to worry me that i am getting one thing after another i am going to docs on friday to check with them i hope it is maybe just time of year and maybe my immune system is a bit weak after having my baby and the lack of sleep, sorry to go on, i think you will be fine but go to docs even if just for peace of mind take care xx
