Hi everyone, 7 months  ago my chin swelled up, I went to doctors who prescribed antibiotics and it went back down2 months later it was back, same again antibiotics and it went down. 2 weeks later it was back again, I tried to get an appointment but couldn't get in and it went back down on its own. Since then it's been up and down 5/6 times. From the past 3 times I noticed a pea sized lump that just stays and the neck under my chin seems to have doubled in size although it doesn't feel swollen. I've been back to the doctors who did a urgent referral to ENT. I've just had that appointment and he can feel the lump and is requesting a ultrasound. He says if it is a solid mass they will do a biopsy otherwise will probably just leave it. Has anyone else been through this or had any advice. It's now another 4 week wait for the ultrasound so I'm stressing wondering what it could be. Thank you
