Health & Medical >> pinched nerve?

while rolling on sat. my neck was compressed. spasms started later that day. i got a massage, and the spasms stopped. sun. morning i woke up and the tip of my thumb is numb. i had another massage yesterday, but it didn't help at all. its very tender around my rhomboid and upper part of my shoulder into my neck. my question is: could this be a pinched nerve? or something worse?

i have an appt. on monday with a physical therapist/chiro to get checked out. should i worry at all? is this going to be a recurring theme?
