Hi just coming on here for a bit of advice and hopefully some piece of mind! I've had a hard lump behind my right ear for about 3 years. It grows and strinks and it always grows when I'm stressed, not sleeping etc. I suffer with really bad anxiety and I've noticed it grows when I'm really stressed and anxious. It never completely goes down but it does swell and go down just not down completely. I've got an appointment with my GP next week to get it looked at. She said as I've had no other symptoms like night sweats, weight loss etc it's probably nothing to worry about but my anxiety is through the roof which isn't helping as it keeps swelling every few weeks and then going back down after a few days because of this ( or that's what I'm assuming) . Is this something to be worried about? I do get headaches quite often, but I don't get much sleep due to my anxiety so I feel like that could be the cause. Thank you
