Hi O Have A Strange Rash That Appeared On The

Hi o have a strange rash that appeared on the palm of my left hand on it is like tiny little clusters . It is not showing any sign of getting better. Now just this week i seemed to feel wierd. Either I can't have a bowel movement or it is diarrhea. I went to er they ran blood test and chest x-rays. Everything came back normal they said. A little dehydrated other that nothing showed up out of place. So now my tummy gurgles alot and I seem to not eat nearly as much as I normally would.cause I get a reflux feeling. Skin feels like a burning feeling . The rash on my hand don't itch at all. I'm sorry so much to ask at once.
