I had a neck kink that lasted what felt like forever. Here's how I got mine to go away- 20-30 minute sessions in infrared sauna 3-5 x week. While in there I would do gentle neck exercises and muscle stretches. I started noticing improvements.

I use muscle relaxer & aspercreme

Over the counter Aspercreme With Lidocaine rub.

Robaxacet is an OTC muscle relaxer and pain reliever. My pain and restricted movement were caused by straining my trapezial muscle.(not sure how that's spelled). I had someone try to massage it out.... BIG mistake. Felt better at the time, but the next day couldn't turn my head,

I had that happen recently😟, where usually heat helps..ice helped that in particular..also i get a lot of help from topical pain relievers, like bio freeze or pain erase
