Hi there... I understand your concern... Take over the counter paracetamol 650mg for fever...hypertension can't be diagnosed in single check up...I would suggest her some dietary modifications tell her to fallow that...she should avoid junk foods,carbohydrates like rice,picked items,packed foods,salt etc,avoid oily foods...add proteins and fibre rich foods to your diet with green tea,green leafy vegetables, fruits...do regular exercise at least 2 hours a day...Consult physician they will do the needful.
