An observation which has become an increasing challenge for mum... She presents with rheumatoid arthritis, not usually a problem but for the past two or three years her hands go hot and cold, of late the coldness has increased in frequency most notably the right hand. Now I understand that 'temperature control' for older people can become a bit of a problem but it affects her ability to manipulate objects; I've used hand warmers, hot water bottles, fingerless gloves with some success but long-term? Any ideas folks? And is this a common problem? I've researched the topic but would like to narrow down the search if I could.
