Neck and Back Pain Combined With a Stomachache After Eating

When you sit down to enjoy a meal you're expecting to have a pleasurable experience, but if you develop pain and a stomachache, you may avoid eating. Neck and back pain combined with a stomachache after eating is most likely minor symptoms of a food allergy. Other conditions that may cause neck pain, such as a gallbladder attack, indigestion or gas pains, wouldn't cause a stomachache. Before attempting to treat your condition, talk with your doctor.

Food Allergies

Food allergies occur when your immune system malfunctions and attacks certain foods that are generally safe. The most common foods that trigger an allergic reaction include wheat, soy, milk, eggs, fish, peanuts and tree nuts, according to The chemical interactions in the body during an allergic reaction to food will cause increased inflammation and swelling in soft tissues, which is the main cause of most food allergy symptoms. Not everyone reacts the same way to food allergies. Symptoms may range from minor to severe and need to be evaluated by your doctor.

Neck and Back Pain

You may develop neck and back pain as a result of swelling in your respiratory system. Respiratory symptoms are common with food allergies, causing increased pressure on your chest, throat and throughout your head. Your lungs can become inflamed, restricting your airways along with sinus inflammation, leading to congestion. Inflammation in your chest can cause pain to develop in your back and neck from increased pressure. Sinus pressure can cause sinus headaches, which can cause an aching pain in your forehead as well as the back of your head and neck.


The American Academy of Allergy, Asthma and Immunology states that gastrointestinal symptoms are common with food allergies because the food comes into direct contact with this system first. Inflammation in the lining of your digestive system will lead to common symptoms of a stomachache. These may include pain, cramping, nausea, vomiting and diarrhea. If you develop severe pain that affects your normal functions, call your doctor right away.

Concerning Symptoms

If you develop symptoms along with neck and back pain and a stomachache, such as hives, swelling in the throat, the inability to breathe, shortness of breath, light-headedness, dizziness, an increased heart rate and a drop in blood pressure, you may be experiencing a severe allergic reaction. A severe allergic reaction could lead to death and requires emergency medical attention, according to MedlinePlus.
