Hello and welcome!
Who is her doctor? Try contacting him to say she is in pain. What medication does she currently take? Is it working? If not, ask them to schedule a appointment to talk about her pain. It is a good idea to ask questions too. Mention your fears and worries at the appointment.
Please tell us more about your mother. What stage of cancer is it? Is it curable or not? How old is she now? This is not okay. No one should have to suffer this much pain alone. I recommend keeping a diary about her pain, with all the details to help. The details of who to contact should be listed on all of her appointment letters. Ring the cancer team in the morning or email tonight asking for advice. What treatments were previously tried? Did they work?
Opioids are commonly used to treat pain in cancer patients across the country. Ask about Fentanyl. Just remember it is a strong prescription medicine however that comes in three forms. Is there a pain specialist you could talk to? Additionally you might find that a pallative cancer care nurse may also be able to help offer suggestions and recommendations.
Make notes during the appointment.
