Since about the 7th I've had a pushing feeling against my right lowest rib some days its worse than others and it seems to be aggravated when I sleep. I can't really feel it when standing up either only sitting down. I've posted images below one where i've highlighted the area I feel the discomfort with a mark for which side it is more prevalent on, also a picture of my neck with my finger placed on top of a tender to touch lump that appeared 3 days ago (don't know if there's a link).
Thank you in advance
