A student knew "something wasn't right" when he was feeling exceptionally tired, even after 18 hours of sleep.
Back in 2018, Tom Hunt spent the summer before university travelling Europe with his friends when he began to feel unwell while in Budapest. Thinking he just needed rest, by the time he reached Prague he began to feel considerably worse.
The 18-year-old decided to cut his trip short and fly home and, after seeing a GP, he was given antibiotics. Tom then noticed a large lump on his leg while on the train, the Manchester Evening News reports, and was soon rushed in for tests.
