I have been getting a numb chin for about 6 weeks now. Sometimes the numbness stretches down the front of my neck and sometimes I get it going up my cheeks. Sometimes it s across the front of my chest. It s like a moving sense of pressure and sometimes it s painful. I get palpitations and the GP is checking me out to see if it might be heart-related. I ve had a couple of borderline ECGs and a borderline exercise stress test. i m currently wearing a 24 hour monitor and I have an echocardiogram scheduled for Monday. The discomfort is really bad today though - chin, bottom lip, across my chest, just a feeling of tightness and pressure. I don t know whether it s stress or if I should get myself checked out immediately.
