Debo, I think because yo goes with -o.
Answer:
El médico le habla a sus pacientes. Le examina el estómago y le da su diagnóstico. Su condición no es grave pero le da una receta para una medicina que ayuda aliviar el dolor. El paciente va a la farmacia y le da la receta al farmacéutico. El farmacéutico le vende los medicamentos que su médico le receto.
I've added 'a sus pacientes'.
On the second line I added 'y le'.
The third line I've added 'que ayuda'.
Last but not least, instead of 'receta' I've changed it to 'receto'.
(Just in case you wanted to know what changes were made) :)
