If you're not sure if your problem is urgent or can wait, you could either
Ask a pharmacist
Pharmacists have a great deal of knowledge and experience. They may be able to offer you help, advice, or treatment, or give you advice on whether you need urgent treatment or not.
There are several "100 hour" pharmacies in the area open late into the evenings and weekends who can offer you advice when we are closed.
... or use 111
111 is a telephone advice service. If you are unsure if you need to be seen urgently, give them a call, and you'll receive advice or an appointment with an out of hours GP at a local GP centre (usually Airedale or BRI).
You can also get advice via 111 online by visiting their website:
