Hi, My bottom lip is becoming dark on either side just like blood clot.My weight is 93KG, Height is 5 10.5 , Age 40. I play Table Tennis and I am a sports person. These days I also feel little bit of tiredness at heart after play or before sleep. At that time I feel little bit tense and a little bit of slurred speech. Is it related to Heart? If yes, what should I take measures? Thanks, Sri
