Symptoms of vertigo. For the same.

My mother has symptoms of head spinning or sensation of room spinning whenever she walks for more time ,she feels better if mask is removed. Sometimes if she suddenly gets up she feels the same. A local doctor prescribed verti star tablets ( he suspected it's due to acidity)  and she took 2 tablets but dint improve much.                             She got hit on the head 1.5 month back from someone's hand ( not a severe one ) she had mild headache ( back of head) for few hours.           About her: She gets headache (back) sometimes from almost 2-3 years whenever the weather is cold or if her head is wet for a long time . She recovered from covid 3 months back (home quarantined) She was Anaemic and was on supplements ( Dexorange) and now her haemoglobin level is 8.5 She has a little asthama history and is allergic to dust and certain food. She has rhinitis ( cold and headache due to cold wind) and even a little sinus problem. She has acidity and takes medications for the same.
