An individual who has frequent episodes of achy pain in the right side of their chest may be affected by pulmonary hypertension, a condition where the blood pressure within the pulmonary arteries becomes too high. Pulmonary hypertension causes the small capillaries in the lungs to become blocked, damaged, or narrowed. Blood is no longer able to flow through the lungs properly, and the lower right chamber of the heart has to work twice as hard to compromise for this malfunction.
Pulmonary hypertension is a progressive condition that becomes worse over time. Symptoms of pulmonary hypertension include breathlessness, fatigue, fainting spells, dizziness, edema in the ankles, fluid buildup in the abdomen, blue tint to the skin and lips, racing pulse, heart palpitations, chest pressure, and pain in the right side of the chest.
