It is very similar to how it feels when a limb “falls asleep” only instead of the sensation going away after you stop laying on that limb in an odd position, it just stays around without any apparent reason and without easing up. This can be caused by some sort of nerve interruption (such as a lesion) in the central nervous system (CNS).
How to Treat Paraesthesia
The pins and needles were one thing but the itching was unbearable! I usually had it on my scalp and I wanted to scratch my skin off! Nothing helped, not antihistamines (like Benadryl), not a cold shower, not even scratching, I just had to deal with it and worse than the physical sensation itself was the emotional frustration of having nothing to do about it: I was helpless.
When the itching is elsewhere it’s like this; imagine putting a sweater made of pure wool on with no under shirt. It’s itchy all over and there is nothing you can do to stop the itching but take the sweater off but guess what? You can’t take you skin off! After a while you may get used to it, not in a “I don’t notice it anymore” kind of way, but more in a “I am just too tired to care” kind of way. “I give up”.
Pins and Needles
I can remember experiencing the pins and needles sensation during small flare ups or when it got too hot. It would start in my finger tips and sometimes work it’s way up to my elbows. This sometimes made simple tasks difficult because it was almost like my hands were numb so I couldn’t properly feel what I was doing. Another frustrating form of pins and needles is when I get it just on the tip of my nose. Not part of my face, not most of my nose, just the very tip so it felt like someone was tickling my nose with a feather; it felt like something landed on my nose but no matter how hard I tried to wipe “what ever must be on my nose” off, the sensation would not go away. Even after I realize that nothing is there it is very hard to not keep wiping at it! I still get this from time to time and I hate it, it’s so annoying!
This is the same as pins and needles as far as what causes it; chance. Sometimes I would have a small flare up and get the pins and needles and other times it was numbness. Very similar to pins and needles I could not always feel what I was doing with my hands (for example). The only difference is it feels more like I could slice my hand open with a knife and feel nothing. There were (and still are) many times where I looked down at my arm and realized I am bleeding without knowing what I did to cut myself. Some people get it really bad in their feet and will step on things like tacks or glass and not realize it until they notice footprint shaped blood spots around the house. I have sort of had this happen but usually I can feel it happen for a split second but in a very dull manor. It hurts but then the pain goes away like “Ouch, what was that? Oh, I just stepped on a nail and it went all the way through my foot” (that never happened haha just an example).
