What could "hot skin" be a symptom of?

Others have given you good information...hot flashes can be from lots of things. One thing that I don't see mentioned is that hot flashes or flush (if her cheeks are also pink) can be caused by medication. Many prescription medications cause hot feelings such as most of the osteoporosis meds like Tamoxifen and Nolvadex, as well as supplements like Niacin (and many more, these are just examples). Additionally certain foods can cause hot feelings..spicy foods, too much pepper, etc. Alcohol can cause these feelings as well as many illnesses like Lyme disease, Guillain-Burre syndrome, and even something as simple as hypertension (high blood pressure). Finally, issues with the adrenal system, particularly the hypothalamus, can cause hot feelings. I agree it's an important symptom to share with her doctor.

Hot flashes should be evaluated and so should the headache. Possibility of stroke for the head pain, or she hit her head and does not remember.
If she has peripheral neuropathy, she may get a burning sensation in her feet or hands. Has she been checked for a fever?

I would consult with her doctor. Pain reports from a dementia patient should be investigated. It could be any number of things. I'd let the medical experts properly diagnose her. Anxiety can cause a lot of different symptoms, but you never know. I'd take proper precaution and consult with her doctor.

My mom had dementia and the pain moved. Ie my head hurts, my stomach, etc and her head feeling hot like a fever. We always attended to any complaint because you never know, but no physical condition was ever found. With dementia the pain or sensations are real to them, but not always due to something else than the mind playing tricks but again, always address with a dr to be sure

This probably has nothing to do with your mother's issues, but just to mention - years ago I knew a lady who had an unusual disorder. Forgive the layman's terms here, but her body "thermostat" wasn't working right and it would tell her that her feet were burning. They would be reddish (it's been a long time so I'm not sure my memory is accurate on that though) , and she had to stay close to home and keep her feet in ice water. She didn't have any kind of dementia though. She was a nice lady; I felt bad for her having to put up with that.

Btw in casei wasn't that clear, although my mom would say her head felt hot, or was only to her. She did not have a fever or ever feel hot to us.

A few things you can look into, 1.It might be a UTI. 2. It might be side effects to any meds she may be taking. Keep track of her blood pressure and take it when her head feels hot. As always check with your doc.

A "Total" Hysterectomy, where both ovaries are also removed, immediately changes your hormones the same as menopause does over time. So yes, you can have hot flashes after a Total Hysterectomy (aka TAHBSO) however, if you had already gone through menopause then the change will be be minimal to none. Doctor will put you on estrogen replacement medication if you are premenopausal. Be aware that long-term estrogen replacement after menopause age may not be wise choice, so question why you are still taking it if you are over 50 yrs old.

I also have 'hot skin' at times and it's very uncomfortable. It doesn't feel anything like a hormonal flushing or anything to do with hormones. I have had it off and on for about 10 yrs now and was finally diagnosed with rheumatoid arthritis 2 yrs ago. I can tell when it's acting up because I get the 'hot skin' feeling like I have fever, and also the pain-- but the hot skin can be by itself. And it is dry and not the flushing type that goes with hormones. The other day I was saying to my husband that my right arm was so hot and he felt my skin and remarked in surprise that it WAS very hot! I guess he hadn't been listening all the other times I commented on it or had me tuned out ;) It is dry and hot or warm. So maybe it is an inflammation in your mother's body? Inflammation is one of the causes of rheumatoid arthritis and when I eat wrong or just have a 'flare' I get these skin issues. Maybe your mother has an infection or even arthritis. There is an easy blood test to determine the inflammation factor in her blood. Good luck!

Make sure she doesn't have any blood clots
