Many attacks are caused by virus or bacterial infections, which usually get better after 2-3 days. Avoid solid food for 24 hours and drink plenty of clear fluids (water or squash). If the diarrhoea is not beginning to settle after 24 hours or there is continuous stomach pain then consult your doctor.
Sit on a chair (leaning forward with your mouth open) and pinch your nose just below the bone for about 10 minutes, by which time the bleeding should have stopped. Avoid hot drinks or food for 24 hours. If the bleeding doesn’t stop then consult your doctor.
Most sore throats are caused by virus infection so cannot be cured with antibiotics. These sore throats usually getter better within 5 days and only need simple remedies such as paracetamol or soluble aspirin and plenty of fluids. If the sore throat is getting worse after 2 days, if there is earache or the temperature is over 39.5 C then you should see the doctor.
Virus infection or eating or drinking too much may cause this. It usually stops within 24 hours without treatment. Eat nothing for 24 hours; drink frequently small amounts of water. As the stomach settles slowly return to a normal diet over 2-3 days. Consult the doctor if there is continuous stomach pain, the vomiting lasts more than 24 hours or in a child with a temperature of over 38C.
