I've pain that started in the right side of my stomach. thought it was muscle pain from being more active but it hasn't passed after 3 days. any idea?

See MD: CCan't tell here. Could br liver, gallbladder,, colon, duodenal, kidney, referred pain from gyn, other. Need an exam ASAP

Probably OK: A young male with isolated right-sided pain for a few days is usually nothing serious and will pass. If it is associated with vomiting, fever, weight loss, altered bowel habits, jaundice or persists, the see a physician. This could be gallbladder disease, ulcers, muscle strain, constipation and a host of other, less likely, causes.
