At 22 years of age, the sensations you describe-such as a feeling of jiggleness in the chest or head during physical activity, fear that the heart or brain may be getting damaged, and multiple body symptoms-are most commonly related to heightened body awareness, anxiety, or dysregulation of the autonomic nervous system, rather than any structural disease of the heart or brain. During activities like running, jumping, or riding a bike, normal body movements, increased heart rate, and blood flow can create unusual sensations, especially if you are anxious or hyper-focused on bodily sensations. These feelings can seem alarming but do not indicate that organs are moving or at risk of tearing-the heart and brain are well protected and fixed within the body.
Since you are concerned about an overall evaluation, the right starting point is a General Physician or Internal Medicine specialist. They can perform a complete clinical examination and basic investigations (such as blood tests, ECG, blood pressure check) to rule out common medical causes like anemia,
thyroid imbalance,
vitamin deficiencies, or heart rhythm issues. If required, they may refer you to a cardiologist for reassurance with ECG or echo, or to a neurologist if there are clear neurological symptoms-but in many such cases, tests turn out normal.
If medical evaluations are normal, which is very often the case in people your age with these symptoms, the next and equally important step is consultation with a psychiatrist or clinical psychologist, as anxiety, panic symptoms, and somatic symptom disorder can produce very real physical sensations without any organ damage. This is a treatable and reversible condition, and addressing it early can significantly improve quality of life.
Next Steps
start with a General Physician/Internal Medicine doctor for a full-body checkup and guidance. You do not need to worry that your heart or brain is getting damaged, but you do deserve proper evaluation and reassurance so that the symptoms can be managed effectively.
