Most of the time our body movements do not cause problems, but it's not surprising that symptoms develop from everyday wear and tear, overuse, or injury. Knee problems and injuries most often occur during sports or recreational activities, work-related tasks, or home projects. The knee is the largest joint in the body. The upper and lower bones of the knee are separated by two discs (menisci). The upper leg bone (femur) and the lower leg bones (tibia and fibula) are connected by ligaments, tendons, and muscles.
Another common sign is the presence of cockroach specks. These dark-colored specks are fecal pellets and regurgitated food, and look like grains of ground pepper. Finally, thereâs the smell. Cockroaches give off a strong, very oily odor, which becomes extremely pungent when large numbers of the insects are present. Aside from all the hygiene issues associated with a cockroach infestation, the smell itself is unpleasant and can permeate food that is left exposed to the air.
Luckily, roaches also leave a tell-tale odor as well as other signs of infestation. When a very severe infestation is present, cockroaches can often be seen during the day. These unpleasant insects are quite distinctive and are easily identified. Between half an inch (1.3 cm) and two inches (5 cm) long, roaches have flat elongated bodies and are colored light or dark brown or black.
