Health complications from hand, foot, and mouth disease are not common.
Some complications include:
- Viral or "aseptic" meningitis can occur with hand, foot, and mouth disease but it is rare. It causes fever, headache, stiff neck, or back pain.
- Inflammation of the brain (encephalitis) can occur, but this is even rarer.
- Fingernail and toenail loss have been reported, occurring mostly in children within 4 weeks of their having hand, foot, and mouth disease. At this time, it is not known whether nail loss was a result of the disease. However, in the reports reviewed, the nail loss was temporary and the nail grew back without medical treatment.
