For about three days now my chest has had a mild pain on the left side.  When I do certain movements, for example, bending over, i can feel a sort of sloshing or gurgling inside.  Also I get a pain in my neck when my blood gets pumping from doing physical activity.
Hello Dear, The chest pain has many causes, the most common are :1- Acute Myocardial Infarction .2- Angina Sectors .3- Esophageal spasm .4- Muscular causes. (the commonest)- Each of the above causes has its own characters, for typical chest pain (cardiac) it is about 15 minutes, substernal and squeezing, relieved by nitrates and increased by exercise, radiating to the back or to the left shoulder and may to the lower jaw.- Muscular causes are naturopathies or myositis (the most common) due to exposure to a cold weather, and will be relieved my simple analgesics.- (blood gets pumping from doing physical activity) may be due to Anemia (Anemic Heart)You should do :1- Visit your doctor .2- Make an ECG .3- CBC.
