2 months ago i woke up with stiff neck. he pain fade out, but since than, i have pain between the shoulder blade with tingling.it feels like muscular?

Radiculopathy: Radicular pain or a pinched nerve in the neck commonly refers between your shoulder blades. Probably still from your neck and time to get it checked...Especially if getting worse.

See a back surgeon: This may or may not be related to cervical spine disease, but you should be examined to determine the cause. The best person to do this is a back surgeon. If this is purely muscular they should know very quickly and advise you on how best to relieve the discomfort, .
