RSA Daily answers the questions readers over fifty actually send us about numbness, burning and balance — without the jargon, and without pretending there is a single answer.
Peripheral nerves are longest at the far end of the body, so the feet are usually where damage shows first. The earliest change is often loss of sensation rather than pain: a sock that feels bunched when it is flat, a floor that feels further away than it is. Pain, when it arrives, is frequently a later stage rather than the first one, which is why numbness is worth mentioning to a doctor even when nothing hurts.
Two ordinary reasons and one less obvious. Distraction falls away when the house goes quiet, so the same signal gets more attention. Skin temperature drops in the evening, and a nerve that has lost insulation responds differently to cold than an intact one. And many people are on their feet all day, so the accumulated irritation peaks at the hour they finally sit down.
Warm water helps the way a warm bath helps anything: comfort, for about an hour. It works on the skin and on circulation at the surface. It does not reach the nerve itself, which is why relief from soaking, menthol rubs and massagers is real but short. Anyone with reduced sensation should check water temperature with a hand or a thermometer, never with the foot.
Numbness that is climbing rather than staying put. A cut, blister or sore on the foot that is not healing. A change in colour or temperature in one foot but not the other. Sudden weakness. None of these are emergencies by themselves in every case, and all of them are worth a same-week appointment rather than a wait-and-see.
