I woke up this morning and i can barely move my arm. it doesn't hurt but it is tingly and i feel a lot of pressure when imoveit. cant fully extend it.

Positional: If your arm feels alright the rest of the day, then there is a positional effect on some structures like a nerve or muscle during sleep only. However if symptoms are present throughout the day, then I would suspect a nerve entrapment somewhere at the neck or shoulder level. An orthopedic surgeon or a neurologist could evaluate,advise and recommend appropriate tests and treatment as needed.
