When a child has a fever and says that his legs hurt, it may be caused by lactic acid buildup due to fever, tendonitis, cellulitis and other reasons.
1. Fever leads to lactic acid buildup: a feverish child can make the muscles metabolize a large amount of lactic acid, and when lactic acid builds up in the legs, both can cause leg pain.
2. Tendonitis: it may be caused by trauma, long-term weight bearing and other reasons. When the child has fever with tendonitis, leg pain can occur due to the stimulation of inflammation.
3. Cellulitis: It is a diffuse purulent infection of subcutaneous, subfascial, intermuscular space or deep cellular tissue caused by hemolytic streptococcus or staphylococcus aureus infection. Due to the release of inflammatory mediators, thus can cause leg pain.
There are many other reasons that cause children to say leg pain with fever, it is recommended to go to the hospital in time, under the guidance of a professional doctor for standardized treatment.
