This is why regular medical check-up is encouraged. According to Boredomtherapy, Hayley Williams, 25, of Binghampton, England, grew concerned when her 3-year-old daughter, Connie, wasn’t healing from a bug bite she received during their family vacation to Ibiza.
“It wasn’t until the next morning when I saw it go black that I thought it wasn’t quite right,” Hayley said. After a blood test, the horrible truth was revealed: her body reacted unusually to the bug bite because she had leukemia.
