She is having headache issue since 3-4 years. Earlier she though it might be because of Gastric issue so when ever she feels this headache used to take Vasogrin medicine in which she gets relief also. But now a days she is having this issue every 2-3 days and she used to take this Medecine. Need advice on what needs to be done. Consult a doctor ?? Is this continuous use of a particular Medecine have any side effect???
