Patient: I was recently seen by my gp who said I had gastroenteritis I visited gp twice as I wasn’t getting better and the first lot of tablets prescribed made me feel worse so he gave me some others.

I still have loose bowel movement, light headedness, low appetite, dry mouth, sweating/cold chills in hands and feet almost like developing of flu but its not..please help?
