I’m so very sorry to read this, the human body is amazing until it isn’t. What a time you’ve had with it all.
Please push the GP for occupational therapy assessments as they’re key to providing all necessary adaptations, rails, slopes, wheelchairs, handles, and so on. Your GP should signpost you to Community OT services, however I’ll post the number again for you. They can help make a huge difference to your husband’s quality of life, which I hope will also help you.
Norfolk County Council Occupational Therapy: Focuses on staying independent at home, equipment, and adaptations. Call 03448 008 020.
Thinking of you and please do let us know how you get on.
