Pinched nerves

Pins and needles going up your neck and face...don't fuck around and see a doctor.

If you've been dealing with that for close to a month there's probably more to it.

Going through that right now myself i have C 3,4 & 5 pinching some nerves and my whole right arm is pretty much useless at the moment well a couple weeks ago now getting much better.
Seeing a Chiropractor who also does Acupuncture, Ultra Sound and soft tissue electro stimulation.

It won't heal on it's own i have put it off for a couple years and now it is chronic and i will be at least another couple months before it's all good again.Of course i'm 61 so if you are younger probably with therapy it will go faster for you.
I would find a good Chiro that does soft tissue work as well they will bring you around pretty quick.

I ruptured my left shoulder rotator cuff in 16 in a moto crash and this same Chiro had me back on the bike in 3 months.
No surgery it will heal better and you will have more range of motion if you do the therapy and let it heal naturally.

Always thought the chiros were “witch doctors” until I tried one. One sure helped me out with a jacked up shoulder that I knew was most likely going to require surgery. He also made some recommendations that helped with my usual 4 trips a year to the ENT doc for my sinus infections. 20 years later I must have slept wrong and it was like the shoulder shoulder injury had happened all over again. Had to find me a new chiro but what a difference it made. Basically taking physical therapy to another level as far as I am concerned.

Last year I'd been seeing a chiropractor off and on who doesn't X-ray to work out some issues with my back and knees; nothing serious really. While it did help I spoke to a friend about it who has more knowledge than I and he recommended another chiro in my area who does full X-rays and a very thorough check. He pointed out why my lower back aches, and to NEVER go to a chiropractor who doesn't see my X-rays ahead of time. One of my lower vertebra are out of place (probably from a crash or that one really big fall/thump 25 years ago), and if it's continually pushed in the wrong direction can case serious harm. I've only been seeing the new guy about a month, but he's slowly trying to get my back back in order. I had tingling in my right hand and it's all but gone away.
Deep tissue massage may help as well, but don't be scared of the back-cracker

Dorsal root ganglion are finicky.

Chiropractors do get a bad rap and there are some who are not any good at all as in any profession there are good ones and bad ones.
Most of the time it is due to someone having something out of place for a long time and the muscles and other tissue attached get used to the new out of place position. When a Chiro moves the bone back to where it is supposed to be the muscles and tissue get traumatized with that sudden movement and of course get painful as they adjust to being torn from their previous position thus folks feel that the Chiro did more damage but really they have fixed the damage and it will take a few days for the surrounding tissue to heal.
This is where the soft tissue manipulation comes in it helps heal it much faster and minimizes the trauma of the adjustment.

If you have had something out for a long time it will get worse/painful before it gets better but they will bring you around if you keep up the therapy.
If you ride a lot or race i would recommend seeing a Chiro at least once a month to keep everything tuned up and in proper alignment so major issues never crop up as your spine really takes a beating on a dirt bike.
