Since last night have a stiff jaw and trouble swallowing, and breathing zeems shallow. ECG in December and 7 day heart trace were normal. Liver enzymes raised but lft normal. Have a neurology appt next month. Very afraid. Could it be anxiety? Please help. Alone with my 3 year old and scared of passing out. Inside of mouth totally numb. Thank you.
