Could The Charley Horse Spasms Be Due To Vocal Cord Dysfunction?

Hi, Our 9 year old granddaughter has had 5 ER visits and was flown to Anchorage. She is now home but… This started about a month ago, their whole family had a doctor’s visit all having strep throat. The morning of the visit she started having a small whistle noise when breathing although she showed no distress of not getting enough air. But by the time she reached the doctor’s office it was getting worse. The doctors did a quick check and said she needed to go to the ER. At the hospital she was in full Stridor, they gave a breathing treatment and took x-rays. The x-ray showed an hour glass shape of her airway with swelling around the airway. Epiglottis looked fine they said. She spent the night in the hospital given antibiotics, doc said tonsillitis . Within the next 7 days she had a total of 4 ER visits and 3 nights in the hospital. Steroids and breathing treatments did seem to help. She was treated for croup. Day 8 she had a follow up doc appointment aDoes nd at that she had a full blown attack. Very bad Stridor, could not get enough air but always o2 was at 100%. She was sent to anchorage there they ran tests checked her throat and said it was vocal cord dysfunction, although the test was not done during an attack.. We have been trying to learn how to breathing differently. But now the attacks are different, they are more like charley horse cramping in the throat, spasms that last about a minute quit a minute and go on for an hour to an hour and a half. Very painful for her. Also we have to watch that her does not panic and hyperventilate. From our reach it feels like there is more than one thing going on, Does this charley horse spasms sound like it is vocal cord dysfunction?
