K First of all im only in seventh grade so don't be mad if it's wrong. Im taking sexed in health and my teacher talked about pain in ur right or left side once a month. It could be that your ovarybis releasing an egg. But idk, that's just a possibility.
what could cause pain in lower left side of a male?
cramp are you dumb
Most likely the lower intestine (colon). When the colon is cramping or is full of gas, it can hurt clear up into the left chest. If the pain is low in your abdomen it can be referred pain from a bad appendix (which is located on the right side.) The spleen is also on the left side. If this pain is always present, or does not go away in a day or two, go see a doctor to rule out anything life-threatening
depends how hard you hit your left side
If a dog is in pain it is advised to see a vet. Pain in their side could be something life threatening.
Shingles can cause localized pain in almost any part of the body. Sciatica can cause pain in the lower back and one or both legs.
Some causes would be, sleeping on left side, sprain, or a strain.
One thing that can cause left side of neck pain above a collar bone could be a stiff neck. If the pain does not go away, one should see a doctor.
Cancer
Such pain can arise due to calculus or stone in the ureter on 'either' side.
IBS
You could possibly have a pulled muscle if pain continues call doctor for pain medicine.
