Does Caffeine Cause Soreness In Lymph Node Of Underarms And Groin?

Good morning - I have been experiencing lymph node soreness in my underarms and groin area , I have been checked by a doctor and could not figure out where this is coming from . It has been coming and going for the last 2 months . I noticed more after alcohol use . I also drink way too much coffee which recently have realized this may be the issue as I feel good in the morning when I wake up then notice it tends to happen after caffeine use . I have switched to decaff recently to see if this helps . Sometimes I was drinking coffee from morning until afternoon . Could way too much caffeine be affecting my lymph nodes ?
