jeeze, you unfortunate bastards with hardcore damage makes my butthole quiver. OUCH!
But there are good reasons why some of us experience cold finger tips and toes...sometimes just one or two digits on the affected hand or foot:
1. Sensory Receptors: There are three kinds: warm receptors that are stimulated by warm temperatures, cold receptors that are stimulated by cold temperatures, and pain receptors that are stimulated by extreme cold or warm temperatures.
Cold receptors are basically the outside receivers on nerve endings, which are intertwined with your capillary circulation. It has been proven that nerve endings are commonly damaged by cold weather injury events, and that even repeated cold weather exposure makes us more and more vulnerable to the slightest of sensory receptor sensitivity. Thus, the older we hunters get (age, injury, and repeated exposure) the more sense it makes that our receptors are deteriorating at the same time.
2. Pain receptors are one problem, but capillary circulation is likely the first variable to consider.
3. Capillaries are the smallest of root fibers s at the tips of small roots of plants...only in our bodies we have billions of tiny vessels that transport warm blood through our tips and toes and to the subsurface of our largest organ--skin. In cold exposure, capillaries constrict to conserve core body temperature...the older we get or the more we smoke or chew, etc...we become more sensitive to cold exposure. Uneven pain, say in one finger or toe or the side of a hand or random cold spot could be caused by nerve damage AND capillary (vaso) constriction.
There are more reasons, but these are the most common water cooler concepts.
It's not uncommon and the only treatment is secured weather protection. You'll have to stay aware of the trouble spot (mine is my right pinky finger) and baby your warmth in cold periods...and avoid nicotine, alcohol, and dehydration.
