Fears of a mumps epidemic are growing after hundreds of people have fallen ill in a UK city.
The students of the two Nottingham universities are among those who suffer from symptoms of the viral infection.
There were about 40 confirmed cases and 220 suspected cases in Nottingham, Public Health England (PHE) confirmed this week.
One student said the infection made her feel like she was "stabbed in the jaw", and had to stay at home for weeks, Nottinghamshire Live reports.
Chloe Glazzard, 20, a first-year journalism student at Nottingham Trent University, said: "I took it about two weeks ago and it lasted about two weeks, so I had to lose some of them. .
"When I first noticed it, I felt like I was punched in the jaw, and my jaw was really sore.
"It made me go hot and cold, I struggled to eat while going very strong and it got bigger, almost like arthritis in my jaw.
"I didn't want to leave the house, I went home to Top Valley and stayed at home all the time."
Chloe continued: "(I) I would say it was an outbreak, I personally know about ten people who have had them, but everyone I spoke to said they knew a lot of people who took them.
"I was taking ibuprofen and paracetamol with codeine, I'm not sure that ibuprofen helped with swelling or not, I personally think it came and went like mumps do."
Symptoms for mumps include painful inflammation and swelling of the salivary glands under one or both sides of the jaw, fever and headache.
Some people suffer from complications that can include inflammation of the pancreas, viral meningitis (inflammation of the brain), inflamed and swollen testicles in men and ovaries in women.
Mumps can also cause deafness.
Dr. Vanessa MacGregor, a health protection consultant, said: "We have seen an increase in data recently and adolescents and young adults who have not had two doses of MMR vaccine are particularly vulnerable.
"For this reason we are working closely with Nottingham Trent University and the University of Nottingham to inform students about mumps and to explain why vaccination is important.
"Graduates and other young adults who have not received the MMR or have received only one dose should make sure to accept the MMR vaccination offer.
"However, it is not only students at risk and we would like to invite all those who have not received two doses of MMR vaccine to do so. MMR also gives immunity to measles and rubella."
To be completely protected, children and adults must have two doses of the MMR vaccine.
A spokesman for Nottingham Trent University said: "Our GP practices have noted a number of potential cases of mumps.
"We have informed Public Health England and continue to support those who have been affected.
"If any student has any symptoms of the disease we would encourage them to visit their family doctor as they normally would and inform an interested staff member in their course if it has an impact on their studies."
The council, NHS and PHE have worked together to address the epidemic.
