The longevity of the ink depends on the pen, but most are about 6â8 months. If the pen dries up, you can try heating up the ballpoint part with hot water in case the rollerball is stuck. Another option is to keep the casing and purchase a refill for the pen. You can find ink refills online in the office supplies section of Shoplet.
Foot fatigue is a common condition that occurs after you stand or walk for long periods of time. The foot muscles become overly tired and cramp, causing the sufferer to experience pain and begin to limp.
Foot cramps have many causes. Some of the most common causes for foot cramps are: Stress or fatigue in the foot â An overworked foot is often susceptible to foot cramps. Poor circulation â Foot cramp is caused by lack of oxygen being carried to the foot. Lack of potassium â This important mineral, found in salt, helps regulate body chemistry and keep you foot cramp free. Dehydration â Lack of water in the muscles contribute to foot cramps. Changing hormone levels â Foot cramps may occur while muscle tissue adjusts to these changes. Pinched nerves â Caused when the electrical impulse from the brain cannot reach the muscle, this can cause foot cramps, numbness and other symptoms.
