Hi all, 

im 27 and have had a swollen lymphnode for 2 plus years in my armpit, I have been to the doctors and seen a couple of doctors and a nurse who have all said it just feel like a swollen lymphnode and did not seem concerned, this made me feel better for a while. I go through stages of touching it and convincing myself it's got bigger even though I don't think it has. I recently had a blood test and blood count test as I have all the symptoms or an overactive thyroid and these all came back clear. I've now stupidly been googling I know the worst thing you can do and have seen a symptom of lymphoma is night sweats which I get regularly. I've now really scared myself and wondered if anyone else had the same? I do have dreams and nightmares every night and have wondered if the night sweats could be down to a anxiety. 
I feel bad going back to the doctors for the fourth time as I've been there 3 times already
