Hi, im 30 and man. i had a feeling of a lump in my throat 3 weeks ago. it got better after a week but i still feel it in the right side of my throat when i swallow my saliva. no issue while drinking or eating. no other symptoms. should i be worried?

If your symptoms is improving you may watch and wait. if it is not gone fully in a month or so, or if it gets worse, it would be prudent to see a doctor. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV and Covid vaccines. Wish you good health!

I'm a bit concerned that you are still having symptoms after 3 weeks. I would suggest that you seek a consultation with a specialist ENT.
