Hi, I´ve been struggling with anxiety for a while, so having said that, everyday I find something different in my breast that feels like a lump and than I realise it´s not, now, 8 days ago I was pressing my armpit, for a change, and at first found something that felt like a lump, but it gets a bit protruded just when I stretch my arm and then shrinks into a tiny chord like a vein, I`ve been pressing it so much for the past 8 days that now I even think it´s a bit tender and sore. Do we have veins that may feel like a small soft lump? If it really was a lump, with it shrink like this and get protruded just when I stretch my arm, probably because of the muscle or something like that under it? Help me please...
