Hi there, I have a lump in my neck. It appeared when my pins and needles down my arm started. i have had a mri scan and the only thing it shows is that the lump appears as a shadow. It doesnt hurt. I now have to wait ten days for the results to go to my gp, then make an appointment with him to get an ultra sound. this has been going on since August. Could this lump be causing my pins and needles? Its at the back of my neck on the right hand side. Thank you
Hi. Thanks for your query and an elucidated history. The lump at the back of the neck can not cause a direct problem of pins and needles in the arm. It is possible that the muscle spasm caused by this lump can indirectly cause nerve pressure or pinching. Get FNAC done of the lump and the MRI should have been done to see if there is a protruding disc causing pressure on the spinal cord which causes the pins and needles feeling in the upper limb as you have. It is wise to get an opinion f a Surgeon for the lump and of the Neurologist for pins and needles sensation in the arm.
