Have you been hit by the 'worst lurgy ever'?
Dozens of people living in and around Sefton have complained of a nasty cold they can't seem to shift.
Social media is full of people sharing their misery over bugs, with one man calling what he is experiencing the "worst lurgy ever".
NHS guidance says if it is just a cold, your symptoms can be managed at home.
You can avoid catching a cold by washing your hands regularly with warm water and soap, not sharing towels or other household items with someone who has a cold, staying fit and healthy, and avoiding touching your face.

If you have a new and continuous cough, a fever and/or a change in smell or taste, you should get a PCR test.
ZOE, the world's largest ongoing study into the virus, said: "A negative result from a lateral flow test is not reliable enough to be sure you're definitely not infected, so if your symptoms persist it's best to get a PCR test to be sure."
