Hello, You suffered from light headedness, vision got blurry, difficulty breathing, started feeling hot and uncomfortable and could barely stand. Your symptoms are indicative of developing toxic shock syndrome, it can be life-threatening, you are suggested to get evaluated by a physician. If you notice any fevers or chills, skin changes, GI distress, or mental confusion, you should get to the nearest emergency department immediately. Avoid using tampons if it does not suit you. You can use pads instead. You should take care of yourself, stay adequately hydrated so that you don t fall deficient of minerals like potassium, sodium, etc. Take home made nutritious food rich in calcium, magnesium, iron and protein. Poor general health condition causes anemia and hence dizziness. Low blood pressure and low blood glucose level also causes symptoms that you experienced. Stay away from addictions if any. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Nupur K., General & Family Physician
