15 month old cough for a month

[Hri23]

Hey, I'm desperate for some advice/help
My 15 month old has had a cough for over 4 weeks now, she coughs so much she goes bright red, chokes and often vomits.

In the past 4 weeks she has had an ear infection, conjunctivitis, multiple fevers and a full body rash.

We've been to various healthcare professionals who keep saying her chest is clear and it's just viral but she is just not getting better.

She won't eat much now which I don't know is because her throat is irritated or whether she is terrified to be sick any more but I feel helpless and don't know what more I can do.

She's on regular pain relief, has a difflam spray for her throat, eye drops and we have a humidifier in her room.

Not sure what answers I'm expecting but hoping someone has a similar experience who can offer some help.

Thank you

It's horrible isn't it. We've had this every winter with my three year old. This year he had a viral wheeze and was given an inhaler as he was struggling to breath and I find that also helps ease the coughing fits more than anything else we have tried. But it usually takes four puffs (he has up to ten when he's having problems breathing). We also put a folded duvet under his mattress to raise the top third of his mattress so that he's not flat at night which helps a little bit.
