Hi
          Stool examination has focused on the basic cause Don't worry,you will be alright with following treatment.But still you are not releaved in 10 days you may need few more investigations.
         
Ascariasis or round 
worm infection affects gastrointestinal &respiratory system as well. The 
amoebiasis  gives rise to stmoach pain. So the symtoms you have are due to a combined effect of both.
      If you are an adult, You should take -
           -Tab 
Mebex 1 rab. to be chewed twice a day after food for 3 days (to be repeated as per dr's advice)
           -Tab. 
Metrogyl  400mg. twice a day after food For 5 days.
           -tab histac300mg twice a day after food for 7 days 
           -cap. neutrolin b once a day afer food for 10 days.
           -Syrup vitazyme 2 sp. twice a day for 10 days.
