Anyone else wake up with a racing heart and complete panic? Vivid dreams. I feel hot frequently followed by cold chills n shakes, night sweats, the highest temp ive seen is 100.3 but 5 min later it was back to 98.5. Cloudy urine, abdominal pain, cold sores. Ive had almost every symptom but ive been testing negative for over 3 months now. Is a false negative still possible at this point?
