Hello,
It would not be a complication or side effect of weight lifting. It is the sign of an infection.
As it is wollen & Painful to touch, I would suggest making an apppointment with your doctor for an an exam, prescription of antibiotics and an accurate diagnosis.
It is highly unlikely this is associated with lymphoma, as you would be experiencing other symptoms.
Enlarged nymph nodes are common and usually resolve in a few days after treatment begins.
Here is some info, let me know if you have further questions:
