My 12.5 year old daughter just started having tremors in her arms, hands, trunk, weakness in her legs when standing. She had been complaining of chest pressure and difficulty taking deep breaths, as well as achy lower back. I had her take 2 ibuprofen, as well as a couple puffs on her inhaler about 40 minutes ago ( she has intermittent seasonal asthma). Her current pulse rate is 88.
