I am very very pleased to share my good news regards to the lump above my collarbone, I have had this lump now which grows and shrinks during the course of the day,I found if I didn't use my right arm too much then the lump would reduce in size,which to me was reassuring.however I attended the hospital and had an ultrasound and biopsy  and the results came to me today. All clear, I wish to share this hoping that it gives everyone with this problem hope and relaxation, please everyone with this problem try not to worry and get it checked out , and relax your mind don't let the fear take over, think positive.good luck to everyone and stay positive.
