I m a UK resident and our online healthcare symptom checker isn t brilliant. I ve tried calling my doctor to no answer several times. I m thinking I will head to the hospital but wanted a medical opinion first as my daughter has chicken pox and we holding up quarantined!! Sudden onset of dizziness and feeling weak, quite irritable, headachy It moved to sudden temperature rise and sweating through clothes, I couldn t move my arms properly. I think it was mental block out tiredness rather than an inability (when I needed to move hair of face I did it automatically it without thinking). Felt very lightheaded and my heart was racing. Then in a split second it shifted to more headachy and extreme shivers. My skin became very sensitive and hurts to touch. I am female, 29 and no medical conditions. This has happened once before, a month or so ago.
