Hi Immunert, I'm happy for you that you found some helpful rehab professionals. As others have said, it would be interesting to understand what precisely they offered that couldn't be offered by a specialist nurse who would have the added advantage of working directly with a specialist doctor, and able to discuss medical issues rather than just lifestyle management.
I don't know what country you are in, but the big argument against rehab professionals in the UK is about them usually being the only clinicians we see, and then only for short rehab courses that are based on false science and potentially harmful advice incluidng increasing exertion. My wish is for that whole setup to be scrapped and replaced by a doctor lead service with specialist nurses who can do regular follow up, management advice where wanted, referrals to other specialisms where needed, and home visits.
Apart from OT's being called in to advise on aids and adaptations such as wheelchairs, and in cases of bedridden patients, physios advising on passive movement to prevent contractures, I can't see any reason to put rehab clinicians in charge of ME/CFS care.
I agree that doctors who want to 'pump us full of medications without any evidence' not being appropriate either. Nobody here is seriously advocating for that. It's not the only alternative to rehab. Since there is no proven effective treatment for ME/CFS, surely what we need is ongoing accessible supportive medical care overseen by a specialist doctor who understands our symptoms and disability, and can prescribe symptomatic treatment meds to help where possible with sleep, pain, nausea and any other treatable symptom,, and keep an eye on severe cases with home visits to ensure nutritional needs are met and appropriate care provision.
