What should I check when only specific areas, such as the back, hands, or feet, feel hot or cold?

Record the temperature felt by touch and the temperature perceived separately

Even if your back feels like it is burning, it may not feel hot to others; conversely, skin temperature may have changed without you noticing it significantly. A description of feeling "hot" is not considered incorrect; actual temperature changes and subjective burning sensations must be recorded as separate pieces of information. A single body heat test is not used to finalize a cause.

Map the location and differences between the left and right sides

Indicate whether it is the center of the back, around one shoulder blade, the entire sole of the foot, or the tips of the toes, and whether the hands and feet are symmetrical. Observe whether the sensation spreads over time or stays in the same place. A newly developed symptom on one side may follow a different confirmation sequence than symptoms that have recurred on both sides for a long time.

Check skin and nerve signals together

Check for rashes, blisters, swelling, redness, or pain upon contact, and whether numbness, decreased sensation, or muscle weakness overlap. For newly developed burning pain and rashes on one side, or rapidly progressing weakness or changes in gait, dermatology or neurological evaluation takes priority over heat-cold treatment. If you have diabetes or diminished sensation in your feet, you must check for burns and wounds daily.

Note the relationship with posture, movement, and sleep

Record recurring scenarios, such as sitting for long periods, posture of the waist or neck, exercise, after lying in bed, or waking up in the early morning. Also observe if these coincided with caffeine, alcohol, meals, menstrual changes, or medications. The goal is to find a recurring pattern rather than assuming a cause based on a single coincidence.

Distinguish between what was confirmed in tests and remaining discomfort

If you have undergone skin, nerve, vascular, or endocrine tests, prepare the test names, results, and parts that changed after treatment. While the fact that no dangerous cause was confirmed in tests is important, it does not mean that the discomfort you feel is absent. Conversely, all symptoms remaining after normal tests Autonomic Nervous Systemall remaining symptoms after normal test results should not be attributed solely to a specific condition or body constitution.

In heat-cold treatment, determine the specific category requiring treatment

If a disease has been confirmed, that treatment is prioritized or continued alongside. If symptoms continue to recur in a specific area, at a specific time, or with accompanying symptoms, Heat sensationand cold sensationthe central goal of Korean herbal medicine treatment is determined through heat-cold pattern identification, whether to reinforce warmth, release congested heat, or first assist in sensory recovery. Cold packs, hot packs, and lifestyle logs are methods to support treatment; do not apply strong temperature stimuli to areas with diminished sensation.
