Thank you for your query. Would you please clarify a few things for me? 1)how old are you - above 40yrs? Are you overweight? Are you male? 2)do you smoke? Any history of heart disease, diabetes hypertension, hyperlipidemia? 3)any family history of heart disease? 4)have you had any surgeries or injury to your chest, shoulder or neck? 5)sedentary lifestyle or any heavy weight training? Your symptoms indicate underlying cardiac (heart) pathology. When there is reduced/compromised blood flow to the heart, it can lead to a variety of symptoms like chest pain/discomfort, sweating, palpitations (the feeling of your heart racing or pounding), numbness/pain along the jaw, left side of neck, left arm and if the flow is compromised outside the heart (like the vessel that supplies blood to the legs)., these symptoms can occur in your leg as well. Cervical (neck area) vertebrae spondylosis (narrowing of disc space between two adjacent vertebrae that cause pressure to the nerves exiting the area) can result in numbness along one side of the body (commonly). I recommend you see your physician. Early diagnosis and appropriate treatment will enable quick recovery and prevent complications. Bloating basically occurs when there is excessive gas formation in the stomach, bowels, and can occur due to improper dietary habits, poor circulation and certain medicines. Hope this helps.. Please get back to us if you have any questions. Wish you good health
