Questions in the Category: Amitriptyline
Neuropathic pain
Please could you explain what is meant by neuropathic pain? Is it different to ordinary pain? And is the treatment any different?
Symptoms: Pins and Needles/Paraesthesiae
I’m in my early forties and have had moderate ME/CFS for about 5 years. I have all the usual symptoms but I now have a new and rather distressing sensation in my arms and sometimes in my legs. It is very similar to the ‘pins and needles’ sensation you can get when your legs have been crossed for too long. These abnormal sensations come and go and don’t seem to be triggered by anything in particular. Is this yet another symptom of ME/CFS? Or do I need to go and see my doctor?
Treatment: Bromelain
I have read several newspaper articles about the use of this natural plant-based treatment for pain relief, especially in arthritis and muscle soreness. But is there any evidence that it can help to reduce muscle pain in ME? Because none of the drug treatments that I have been prescribed by my GP have helped.
Treatment: Selective Serotonin Reuptake Inhibitors
My doctor has suggested that I might like to try using a drug called sertraline (trade name is Lustral). I know it’s normally used to treat depression but he says that it may be worth trying because ME can upset the levels of chemical transmitters in the brain and this drug can help to increase the level of one called serotonin. Is this drug safe? And is there any evidence that it can be used to treat ME?
Symptom: Vivid Dreams
Are vivid dreams a recognised symptom of ME? Like most people with ME I have unrefreshing sleep and sometimes wake up in the night. But I’ve recently been waking in the middle of the night with very clear memories of rather bizarre vivid dreams. Fortunately, nothing frightening has happened so far!
Symptom: Nerve Pain
Like most people with ME/CFS, pain is a fairly constant and frustrating symptom. But this has become more persistent and severe over the past few months. My GP has prescribed various pain relieving drugs – including low doses of amitriptyline and gabapentin – none of which has had much effect. As well as the pain, which often has a burning quality to it, the areas around it sometimes feel numb and strange. I’m starting to feel quite depressed as a result – is there anything else that could be done to help?
Symptom: Tinnitus
For the past few months, I’ve been hearing strange hissing and clicking noises in my ears. Not surprisingly, this makes concentration and sleeping even more difficult than usual. My GP has diagnosed a condition called tinnitus. He says it’s quite common and there’s not much he can do to help because drug treatments aren’t normally very useful. I have heard that tinnitus is more common if you have ME. Is there anything you can suggest that may help?
Treatment: Drugs and Weight Gain
Although taking a low dose amitriptyline has been very useful in reducing some of my pain and helping to correct my very erratic sleep pattern (frequent wakening during the night) I’ve put on a considerable amount of weight since taking this drug. My GP says that weight gain is a well recognised side-effect with this type of drug and that it can also occur with other drugs that are used for pain relief. I know from talking to other people with ME that weight gain can be a major problem with some drug treatments for ME. But why is this so? And are there any solutions?
Mast cell disease
I've read on the internet that there is a condition called mast cell disease that has a number of symptoms that overlap with ME/CFS. Mast cell disease can also cause allergic symptoms. I've asked my GP about this but she doesn't seem to know anything about this disease. Is this something that I ought to pursue?
