Hi,
Noted your detailed history about
diarrhea, headache that is not responding to routine medicines, are sleep deprived due to three kids at home.
Since there is history of diarrhea with headache and intolerance to heat, the most probable cause looks to be intestinal infection.
Hence I would advise you the following situation:
Consult a Doctor for clinical evaluation, examination and get the tests of stool, blood and urine.
Ultrasonography of abdomen.
This will give proper diagnosis.
You may thus require a course of an antibiotic,
metronidazole and probiotics.
Treatment of the original disease will help to alleviate symptoms till then continue on symptomatic and supportive management. Tell your Doctor that you have 4 month old child and if you are
breastfeeding to give the medicines that are safe for the child.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, General Surgeon
