Two of the most common types of faucets on the market today are cartridge and ball faucets. Cartridge faucets have a hollow metal or plastic cartridge insert that seals against the spout or faucet body. Depending on how a series of holes in the cartridge align with the stem, water is mixed and controlled. Drips usually mean the cartridge needs replacing.
Bone infection is also a common cause of front thigh pain. It occurs as a result of bacteria that affects long bones. Normally, bone infection or osteomyelitis can be chronic or acute, and it is characterized by tenderness of the muscle, inflammation of the affected bone and pain when sitting.
Pain that is 'burning' is usually associated with injury to the nerves. Sometimes burning pain down the thigh is caused by something called meralgia paresthetica which refers to compression of one of the big sensory nerves to your legs. I don't know if that can cause pain all down to your ankle or not.
