My husband is 32 and first started getting neck pain (back of neck) on Sunday, and by Monday during the day it became so bad that his range of motion became very limited. There is no known cause as to why this began. He developed pain while swallowing (on Monday). The front of his neck feels bruised. He also said it feels as if he was screaming all night at a rock concert. The most painful motion is when he tries to tilt his head back. He could only turn his head from side to side at about a 45 degree angle. He could tilt his head from side to side without much problem. He could tilt his head somewhat forward, although it felt bruised. He has never been able to touch his chin to his chest without excruciating pain since he was a child (it hurts his right back shoulder). The pain location is along his spine at the very base of his neck. It doesn't hurt to press on at all. He said it feels as if it's on the inside of the spine.
Another thing that started on Monday at about 4pm was that he lost up and down motion in his right wrist and right foot. He said the tendons felt really sore and it was impossible to move. We are not sure if this is related.
He went to the emergency department on Monday evening, and they conducted a blood test and x-rays. The blood test showed no infection (he had no fever anyway). Previously, he was tested for rheumatoid arthritis and the results came back negative. X-rays were done on multiple angles: front, side, front facing upward with mouth open, front facing straight on with mouth open. The doctor said that his x-ray results came back "normal" and that there is no bulging discs (we asked about this).
The pain has become significantly worse and the pain while swallowing is worsened as well. His range of motion in his neck is becoming even more limited and the pain is getting worse.
Any ideas as to what is going on?
