Her blood pressure of 127/60 is not low, but shivering and body aches after 5 days with almost no food and only limited water need medical assessment today, especially if symptoms are ongoing or worsening. This could be dehydration, low blood sugar, electrolyte imbalance, or an infection that happens to be starting.

Seek urgent care now / emergency care if she has confusion, fainting, severe weakness, chest pain, shortness of breath, repeated vomiting, cannot drink, very little or no urine, fast heartbeat, fever with shaking chills, or worsening symptoms. These may signal serious dehydration or another illness. MedlinePlus lists confusion, fainting, lack of urination, rapid pulse or breathing as emergency dehydration signs.

Even without those danger signs, because this has lasted 5 days and she has shivers/body aches, arrange a same-day clinic or urgent-care review. She should go sooner if she has diabetes, kidney/heart disease, is pregnant, or uses insulin, diabetes tablets, diuretics, or blood-pressure medicine.
