What a horrible pre- diagnoses its a shame they didnt do all the tests before scaring you. Im lucky enough to have not had any experiance with this but I wish you well what ever to outcome. Im not sure, It sounds like you are young and may people get through it with flying colours.
Although this is jumping the gun. If in worst case have you read of sperm harvest? as Ive said I have no idea if treatment in worst case would effect quality. But keeping your taddys safe for later
Im sure or hope its nothing to worry about, good luck.

HEY MAN,,,THIS IS JUST MY OPINION AND IM NOT A DOCTOR SO NO ONE NEEDS TO HARASS ME..................,,,Its normal,,Ive been there and freaked out and that was 20 years ago. I was the same age. I got sick just like you and everyone else, my lymphs swole up in my neck,,the soreness went away but they stayed large...STOP pressing them and poking around, that can make them sore too. The only way to know is to get a biopsy, but man it happens to lots of people. There are also things you can do to increase lymph flow , like jumping or jogging, excercise may make them larger..I seriously thought I had lymphoma..The nodes stayed larger for months and I finally forgot about it,they are normal now. At the same time a 16 year old kid I knew died from lymphoma, so it DOES happen.But could be just normal.
I have this traveling thing that happens every year,starts in the nodesround my tonsils,then goes away but starts in my jaw then to the back of my head. I never feel sick but its kinda painful to touch and makes my eyes water. I have to deal with that bout a week outa the year...I nevr get sick anymore though, not like the time I was your age.
I would recommend buying a juicer if you dont have one. Buy organic carrots,beets,greens and your fave veggies,,a good strainer for the pulp and drink up,,eat lots of colors (not artificial) like blueberries,,strawberries and any fruit or veggie with bright colors...if you need some good easy delish recipeslet me know...`DONT EAT JUNK IF YOU DO...Go to Wholefoods or somewhere and buy groceries,, I did.still do
Its really interesting learning about antigens and how the lymphatic system works. good Luck...

I wish you the best...but you did state here posted from your OP...that several things were not clear:

"They said that there is either some kind of infection going on in my body, or that I have lymphoma..."
&
"...started suspecting now both infectious mononucleosis and lymphoma, but more likely infection mononecleosis (its INFECT-IOUS)

I would try to control the stress until you know....seems 50-50 by your own words.

Let us know please.....Blessings

My cousin was diagnosed with lymphoma when she turned 20. She just had a bone marrow transplant and everything is looking great. In five days she will officially be in remission.

Its scary, I know....but not necessarily the end of things. Sending love and best wishes your way....

Please, in case I will be diagnosed with it.. I dont want to be treated with radiation, I know what it does, I read a lot about it. I want something effective, some kind of alternative therapy. What could work? Thank you.

Very sorry to hear of your health issues. Hopefully it's not cancer, sometimes doctors try to lay out the worst possible scenarios to prepare the patient "just in case". So you may not have it. But if you do, the radiation treatments are not the end of the world. My dad had throat cancer and underwent radiation treatments, it resulted in some burns on the outside of his neck (like a bad sunburn) and he had a painful sore throat for a while. But it did work great and he's been cancer-free ever since. Good luck to you.

I am sorry to hear about this. There is no way for me to imagine what you are feeling right now but I truly hope you have good news when you get your test results.

Best wishes and a speedy recovery

I had cancer and went the chemo and radiation route. Don't jump to conclusions and think death sentence. We will be here by your side to help you deal with whatever you are facing. Wishing you strength and couarge and lots of love! HUGS!!

Remember, you haven't been diagnosed yet so remain optimistic.
And stay away from search engines trying to find answers.
You will only get. Negative responses, like if you wrote in webmd about having a headache
And dizziness it would say you are having a stroke lol.

Stay strong my friend.
Optimism works. I have been told I'm a hyper optimist but no reason to think the worst.

Good luck and keep us updated
