After taking a bath or doing some work for a long time, she feels tired and get headache sometimes with vomiting sensation. The headache lasts for a long time and when she lies it go away. So she prefer to sleep and also she didn't eat when she feel like that becoz she thinks that it brings vomiting sensation. Sometimes, when she gets headache and vomit, we could see undigested food. We couldn't find the actual reason for this headache. Kindly give a clear idea on why it is occurring and how to avoid it in future with natural remedies. If not possible, Pls provide some medication.
