Gallbladder disease, kidney stones, liver disease, muscle spasms and gastrointestinal disease are potential causes of aches on the right side of the body, according to MedlinePlus. Individuals with blood in the urine, continuous unexplained pain, and pain combined with nausea, high fever, vomiting and chills should consult a physician.
Aches on the right side of the body may also indicate appendicitis, advises WebMD. If left untreated, the appendix may burst, spread infection and create health complications.
Specific to women, pain in the right side may indicate an ectopic pregnancy, which is a life-threatening emergency, explains WebMD. Women should seek treatment immediately if nausea, vaginal bleeding and dizziness accompany the pain.
