My nephew had little spider bite bumps on his upper thigh. Then later that night he had a fever and was up all night crying. In the morning his parents noticed he couldnt crawl and he wouldnt walk. They took him to the doctor and she admited him to the hospital. They said it is an infection and they tried draining it but than said there is nothing to drain. Ever since they've been running tests and have'nt been able to figure out what it is.
