I have a 6.4 cm tumor extending out of my T-3/T-4 spinal nerves extending out to the edge of my left lung closest to my esophagus. I have been asymptomatic; however, recently, I have been feeling slight discomfort on my left deltoid, trap and lat muscles. At times I have a feing of back pain in the middle is spine. I take adderral 10 to 15 mg every other day. I noticed that this discomfort is less to non existent when I don t take my medication. Does adderral trigger the pulsation a of those nerves to cause this discomfort on the left side? Also, does it have an impact on tumor growth?
