you could have tennis elbow,or you could have a pulled muscle,not sure how they treat tennis elbow but it similar to what you are describing,another reason for these feelings could be a trapped nerve,go to your docs to have it checked out
loss of flex-ability could be caused by a calcium deposit on the disk of the joint. u need a ex-ray to determine if that is the cause. The tingling sensation is a bit scary and could be related to a heart/stroke condition. See a doctor if it happens again....
