Hi i had my 2nd co vide vaccine a year and a half ago the next day i had a huge lump which was a swollen lymph node it went down but after 3 months the lump was still there it is moveable and not painful I went to the doctors and the doctor said if it still hadn't gone down in 3 weeks to go back so i do leave it until a year later the lump is still there i go back to the doctors they do bloods and he says its a muscle. The lump is still there now the bottom of my back aches a lot and this last 3 weeks I have had this weird pressure feeling in my chest? I'm going to ring for another appointment tomorrow. Do any of you think I should be concerned?
