I also started off with the pain on my elbow. I would massage my arm, and the pain would move around in all the front muscles of my arm. When it reaches a finger, it sometimes have a "pinched nerve" feel to it.When lifting even light weight items in the kitchen the pain would be in the fingers.
I was shocked at the pain I experienced when I picked up a pillow by using more the fingers than the actual hand.
The pain in the arm started keeping me awake at night. At the same time I also have a spot adjacent to the ankle that would normally start aching with the onset of night. This I had put down to tendonitis.
I have now seen a homeopath who checked my acid levels. Too high acid levels. I have to now remove certain foods from my diet to increase the alkalinity in the body.
I'd also ask if you have a difference in the temp of your skin from left to right arm. Also, is there a difference in the color? Are you right handed and lastly, have you had any IV's in the right arm recently?
How long has this been going on? What have you tried to relieve your symptoms? Does anything help? Does anything you do make it worse? Have you seen a doctor? Do you have any other symptoms?
