The shelf life of paint depends on the type and whether the paint container has been opened. Solvent-based oil or alkyd paints can remain usable for up to 15 years if they were never opened and always kept away from temperature extremes. Water-based acrylic and latex paints can stay good for up to 10 years if never opened and kept from freezing. Leftover paints that have been opened should be closed up tightly, stored in a cool, dry place and used within two years. Paints normally separate into solids and liquid during long-term storage.
In addition to causing pain in the upper left abdomen, a few causes (bowel cancer, enlargement of the abdominal aorta, food poisoning, infection or kidney stones, trapped gases, etc.) may be the cause of pain in the left lower abdomen.
Pain on the side of the left upper quadrant of the abdomen should not be immediately attributed to the spleen. A number of other causes of pain in this area are discussed in the articles below and should be investigated and excluded before diagnosing spleen pain. 1  Gastric Pain (Stomach). 2  Kidney Pain Location (also refer to Causes of Kidney Pain).
