my 13 yr old daughter has been experiencing dizziness and her heart feels like it flutters after the ER,drand heart specialist visits we learn shell be fine by drinking 40oz gaterade and water everyday. it has been cpl mths of good results but now her symptoms are back plus the veins in her wrists are now hurting too. shes been under a lot of social stress and anxiety. im wondering if this could be panic attacks?
