DD (3yo) has had a really hacking (for want of a better word) for over three weeks now, she's only vomited once with it, but it's causing her to retch and bring up a lot of wind. She's also complaining of a pain in her ribs at the front, I think this is muscular due to all the coughing.
I've taken her to the gp and she's had her chest checked twice and it's fine, they can't find anything physically wrong but it's gone on so long I'm now getting a bit paranoid. Any advice would be appreciated.
