[MyDaughter79]

My 11yr old daughter has had a chronic dry cough for years now, since November she had strep 3 times, h influenza and now rsv, she is having a sever problem wearing all types of clothes causing her to make twitch motions, she can’t wear a bra because it drives her crazy , only certain clothes she can wear which is very limited and then they are an issue, now when she showers her hands swell up then when the swelling goes down there’s a slight dry rash, her cough/throat clearing is all day throughout the day. Me and my wife are loosing our minds, we’ve been to so many doctors and no one can figure it out! Any help would be great!
