I feel pinching sensation in chest. It's not very very common but occasional. When I feel I have had lot of fatty stuff in meal or non veg. It will be common when I stop exercising. Some times I feel sudden momentary stopping of blood supply to some part of chest and back. That part of muscle feels sudden gasp of air. (Breathlessness). Please suggest a doctor nearby me (neural expert) and prevention method for blocked veins. Thanks
