Hi I've had a lump at the back of my ear for 3 years now it swells and grows every week or so. The lump feels hard at the bottom and doesn't move (I'm not sure if it's because it's on top of a bone) but the middle/top of it feels a bit squishy. There's like a pea sized circle at the top that feels detached from the lump and each time before it goes back down when I move my jaw I can hear a clicking noise coming from the lump as it's right behind my ear and then what sounds like a wet noise like there's fluid inside but it still feels hard. I have been to the doctors, he said that he thinks it's a swollen lymph node due to swimmers ear and if it doesn't go down in a few weeks he will refer me from a scan. I have no other symptoms at all, other than the occasional headaches. I suffer with mental health (severe anxiety, OCD and depression) and I've noticed that when my mental health is bad (I don’t sleep or eat when it's bad) it swells but I don't think stress or anxiety could cause it to swell. It never completely goes back down, but when it does it's not that big just raised. I'm just concerned as I've had it for so long, it swells so often and I thought lymph nodes were meant to be movable and not hard. Nothings changed since I went to the doctors, he gave me ear drops but I felt like they wasn't going in to my ear like something was blocking it. I sometimes get a sharp pain in my ear too, so I'm not sure if the lump could be related to a problem with my ear. If anyone could give me some advice I'd really appreciate it, I'm terrified of going for a scan because I always expect the worst when it comes to my health. I went to the hospital a few weeks ago as I felt like I was struggling to breathe, they did blood tests, a chest X-ray, an ECG, my oxygen levels etc and everything was normal. I was prescribed Lisdexamfetamine for my ADHD a week prior, so they said they think it could be a side effect from the medication or an anxiety attack. Since coming off the medication my breathing has gone back to normal
