Hi. My left submandibular gland (salivary I'm assuming) has been swollen for a little over a month.
There is occasionally slight pain, but I haven't been able to correlate it directly to eating. I don't have any dry mouth symptoms. I tried massaging it once and had pain for a while afterwards. It is moveable and seems to be as large as the tip of my thumb, but is only palpable, not visible.
I checked for swelling of lymph nodes, and thought that one or two behind my left nipple felt a bit larger than the ones on the right, but this may just be paranoia.
My question: Is this cause for concern right away, or can I wait 2-3 weeks until I am back from my internship to visit my GP?
Other details: Healthy 23 y/o male; visited GP for gastro-intestinal problems earlier this summer.
