Hello,
Three conditions are stated here
cough, ringworm, blood stained stool and these are not related with each other, cough could be allergic one and most of the time may not need any treatment but goes away on its own.
If the symptoms persist for days, then it demands the investigation to ruled out the infection or systemic disease, blood stain stool could due to diet and may not blood itself unless it is being confirmed.
Fissures in this age are not less likely,
constipation some time causes the bleeding per
rectum, for ringworm anti-fungal local application will help like
Miconazole cream, (Symptoms of cough more than couple of week need to be taken for investigation like x-Ray chest, and blood work).
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Husain
