2 lumps in right side of neck just below jawline

Hi all,

i'm a 21 year old mum and been having an awful time with my health recently. A couple of months ago on holiday I just had such strange sensations going on in my throat and felt like I couldn't breathe properly due to a swelling feeling. Ever since I have not been the same and been suffering from panic attacks/anxiety because I am so worried. 

I've had difficulty swallowing/breathing, sore theoat, swollen tonsils, chest pain, headaches, fatigue and an overall sensation of lump in throat (which I'm not sure if it's bcos I'm so anxious about it all). The GP is putting it down to acid reflux and anxiety. However, I've now noticed a lump(s) in my neck a couple of weeks ago which I thought were just swollen glands. However these are higher up than normal, incredibly hard and I think have grown ever so slightly.

it's only on my right side and they both sit right under my jaw. Since being poorly no one has even done a gland check on me so I'm worried something could have been missed

has anyone had a similar experience? I've expressed my conerns and they've open spoken to me via phone and now just ordering thyroid blood tests at the moment.

i just feel in my body something really isn't right I'm so breathless by walking and I'm a fit 21 year old who loved exercising. It's making me feel so down and I'm worried something is really wrong :( x
