Welcome to Justanswer! I am Dr. Altman and happy to assist you both today!
I am so sorry to hear your little one is showing these signs.
I can give you basic guidelines for him but if this is not improving or worsening please seek veterinary attention asap
Ideal is to have your veterinarian first thing tomorrow evaluate your dog to definitively diagnose the problem and start on appropriate medication to control the discomfort. Until you are able to do this please restrict activity (which often they are already doing themselves but that means no steps/ stairs and only carrying to go potty) and rotating warm and cool compresses on the neck in ten minute intervals to reduce pain and increase blood flow.
You can also do light circular massage up and down the neck to stimulate blood flow if this is not too painful and will allow it.
To pick your dog up please use one hand between front legs and then scooping behind back legs to avoid pressure in the middle of the back. I have actually trained my little dogs to put their front legs on my forearm to minimize pressure on their backs and the associated discomfort.
Unfortunately we are very limited in over the counter pain medications, especially because your vet will be prescribing something more effective to get him comfortable tomorrow.
Here is a pain assessment form to review. If he is >2 then I would advise a veterinary er tonight to give him relief
You can try benadryl at 1 mg/pound every 6-8 hours which will help allow him to rest and put his head down if he is able. Please elevate food and water bowls to chest level to allow him to eat and drink.
Please let me know if you have any additional questions I can assist with. I hope you are able to get your little one comfortable soon, truly.
