( 17 , usually healthy I think ) So around this time last year I went for scans on a lymph nose in my neck which I had been worried about and they said it seemed fine and could stay swollen due to my acne on my face  ? And since then I've had a few other concerns one being wheezing when I breathe out heavily this came on quite sudden and hadn't eased off since around 2/3 months ago maybe even longer , I recently contracted covid which hasn't helped as I've become quite breathless but I noticed my lips began to swell around day 4 of having covid and there are these patches inside the lining of my lips which look like a little rash almost and they are a little sore , my lips have swollen for no reason in the past and it almost comes and goes I'm just a little worried and I'm not sure wether to ask 111 for advice or try and see a doctor as I've also been experiencing chest pain which comes and goes every so often I tend to Google most of my symptoms and they all lead to cancer one way or another  . Is there any advice someone can give me please ?
