There are fears that headaches are growing after hundreds become ill in a UK city.
Students from both Nottingham universities are among those suffering from the symptoms of the viral infection.
Around 40 cases were confirmed and 220 suspected cases in Nottingham, Public Health England (PHE) was confirmed this week.
One student said that the infection had made her feel that she had been punched in the jaw, and that she had to stay indoors for weeks, reporting Nottinghamshire Live.
Chloe Glazzard, 20, a first year journalism student at Nottingham Trent University, said: “I had about a fortnight ago and it lasted about two weeks so I had to lose some universities.
“When I first noticed, I felt like I had my head in my chin, and my chin was very sore.
“It made me get hot and cold, I found it hard to eat because it got very hard and bigger, almost like arthritis in my chin.
“I didn't want to leave the house, I went back home to Top Valley and just indoors I stayed for a while.” T
Chloe continued: “[I] I'd say it's a new case, personally know about ten people who got them, but everyone I spoke to told them they knew lots of people who got them.
“I was taking ibuprofen and phacetamol with codeine, I'm not sure whether the ibuprofen had helped with the swelling or not, personally I think it's just come and gone as it is; the heads do it. ” t
The symptoms for headaches include painful inflammation and swelling of the salivary glands under one or both sides of the jaw, fever and headaches.
Some people have complications that can include pancreatic inflammation, viral meningitis (meningitis), inflamed and inflated testicles in men and ovaries in women.
Headaches can also cause deafness.
Dr Vanessa MacGregor, health protection consultant, said: “We have seen an increase in the figures recently and teenagers and young adults who have not had two doses of MMR vaccine are particularly vulnerable.
“That's why we are working closely with Nottingham Trent University and Nottingham University to inform students about headaches and to explain why vaccination is important.
“School leavers and other young adults who have not received the MMR or received only one dose should ensure that they receive the MMR vaccination.
“However, it is not just students who are at risk and we would encourage all those who have not received two doses of MMR vaccine to do so. MMR also gives immunity to measles and rubella. ”
To be fully protected, children and adults need two doses of the MMR vaccine.
A spokeswoman for Nottingham Trent University said: “Our surgeries have noticed a number of possible cases of headaches.
"We have informed Public Health England and continue to support those affected. T
If any students have any symptoms of the illness, we would encourage them to visit their GP as they would normally do so and inform a relevant member of staff on their course if they are 39 impact on their studies.
The council, the NHS and PHE have been working together to deal with the case.
