It could be either just peripheral neuropathy or fibromyalgia. In fact I have both post 2nd SCT and it’s a life of daily pain and inability to move about a great deal at times.
As well as widespread pain, people with fibromyalgia may also have:
increased sensitivity to pain
extreme tiredness (fatigue)
muscle stiffness
difficulty sleeping
problems with mental processes (known as “fibro-fog”), such as problems with memory and concentration
headaches
irritable bowel syndrome (IBS), a digestive condition that causes stomach pain and bloating
Considering the obvious discomfort that you are in, you need to speak to your Consultant or key worker as a matter of urgency to talk about diagnosis and possible treatment. There is no medical test or actual treatment for fibromyalgia, just a chat with a specialist who will ask some questions. Fibromyalgia isn’t uncommon after either a major trauma or medical treatment.
On the treatment side there are things that can help, but sadly having tried most of them they just lessen the pain and stiffness. Also get them to check your scans for signs of arthritis and perhaps a blood test for raumatoid arthritis, which isn’t the same as arthritis, but a closer cousin of Myeloma. At the very least you appear to need input from the hospital, diagnosis and perhaps referral to the pain management clinic.
