I have put off fixing a broken bridge and several broken teeth on the left side both to and bottom. I have no ins and can't afford the cost. It's been for about 3 years and the teeth have gotten worse but no pain. I started suffering from neck and shoulder pain 4 months ago. It has become unbearable the pain usually starts at the base of my neck and crawls either to one side or the other both directions. I feel a lot of pressure lately behind my ears at the back of my skull. It 's very stiff and relentless. Ive tried everything else massage, ice, heat creams rest everything I can imagine. The pain is so bad now I may have to see a dentist or find one who may be able to help me

YES of course. Infection spreading. Abscess pressing on nerves. Both! You have lymph nodes around where you are feeling pain and they may be trying to fight infection, and losing the battle.
Please pay for an oral surgeon, not a dentist, and this stage. I speak from personal experience. Since you will probably have to have some teeth removed, plan on about $300 per tooth.
