Is this like a stinging tingling? If so I have that too and other pains in my left arm nothing heavy very slight pains.Anyway, I do not know of yet what the cause is but its been ongoing for months.Had the stress test with echo and all that jazz nothing yet.Sorry im of no real help but I figured id respond since no one else has......
I get the same thing. Mine is caused by a pinched nerve in my neck. I was sent for an MRI where they found three herniated discs and three buldging discs. I thought it was heart related but never mentioned to the dr. I was only sent for the MRI because of tendonitis in the elbow on the opposite side.
Rotator Cuffs are so very fragile and when the inflame, they can hurt like hell.
Treat them tenderly and the usually heal.
Once I was carrying 2 shopping bags of groceries through the mall and my right rotator cuff spasmed insanely, and I let out such a SCREAM involuntarily...then embarassedly looked around to see about 50 people looking at me///
