I was unemployed for 2 months and felt fine, I recently got a job a month or so ago waitressing.
For the last 2 weeks I've been having a tingling sensation on the left side of my back about midway down.
I am left-handed, just like the other person here who has the sensation on the left side.
It comes and goes, it has no pain and as far as I know I do not have a dark patch of skin where the sensation is.
But it does itch quite frequently.
My guesses is that: a, I have a damaged nerve and it's not sending the proper signals to that part of my body.
b, I could have that thing called shingles or something... not sure what it is, cuz I always thought shingles were things on your rooftop.
c, it could be some sort of nerve disorder or carpal tunnel for your back.
All of us have similar symptoms yet nobody has been able to really say anything about what it truly is.
I think the best thing to do is go to the doctor, or figure out of doctors can do major research on what this is.
I've had the exact same thing ever so often. I'm pretty sure that I know what the problem is. I call it "Endorphin Deficiency Disorder (EDD)". I'll later explain how to test for it.
In my case the itching/parasitic feeling starts right below my right shoulder and then spreads out depending on my posture.
The idea is that certain nerve hotspots naturally exist in the body, like how tree growth is asymmetrical. Nerves are effected by mechanical stresses (movement/exercise), chemical stresses (endorphins, toxins) and viral activity (like herpes). Ultimately all effects are obviously chemical in nature. Problems arise if there aren't enough endorphins. I assume that the stresses on the nerve are almost always "natural" or at least not acutely serious.
The test: Slap yourself on the thighs with flat hands, possibly on your bare skin so that it actually hurts. Feel if you still notice the itching on your back while you're doing this. If it goes away you indeed have EDD. See how long it takes for the itch to come back after you're done making endorphins.
Remember: Homo Sapiens was originally a nomadic species and later became an agricultural laborer. Some thermostats in the body just aren't set to sit still like a statue all day. The best medicine against pain is often more pain! By trying to get as comfortable as possible by slouching, turning up the central heating, drinking hot beverages all day, etc, etc you’ll just end up feeling like sh*t. It isn’t even just in your head! The body needs to be challenged! The solution: Don't sit still all day; challenge your body; do pushups; fast pace walking/running, etc, etc.
I've been having the same sensation, but I think spekzondernek is on to something, it does feel slightly relieved when I go walking. I feel it on the left side, more towards the front although sometimes towards the back, and sometimes towards the front as well. Been feeling this for months, and doc has no idea what it could be, but suggested it might be inflammation affecting a nerve.
Just wondering, but does anyone feel any other strange sensations when the tingling starts? Sometimes, I feel tingling near left eye where the tear duct is, or sometimes even on my left testicle. Most of the time it's on the left, and since they happen at the same time I feel they must be related. If it is inflammation, then I think it might be a nerve that runs down the body. Maybe someone has a better idea what it could be.
