If you have osteomyelitis, you may have severe pain in the area where you have the infection, swelling and a warm feeling in the affected area, a feeling of being unable to move the limb where you have the infection(in children, this means the child will not move the affected leg or arm), a fever(sweating, especially at night) and a feeling of general illness, and pain or muscle spasm in your back, if your spine is affected. Although these symptoms aren't necessarily a result of osteomyelitis, if you have these symptoms, visit your doctor. If you have a chronic infection, you may also notice a discharge of pus at the location of your infection. If you have this symptom, see your doctor.
