Hello Dr...l was cleaning our litter box and must have had my neck at an odd angle...well, a few days later.my neck a t the lower left backing started to hurt and had / pain on one side....feels like a hot poker with some palpitations l can feel. At times...l have been taking two Tylenol every 4 to 6 hrs. My Dr wants me to take Tylenol only. A PA prescribed federal for me..a every low dosage...l took one when l got. Home This happened before. But not.as severe...lt burns like l am being branded!
