Could lymphnodes result from a foot infection?
Lymph nodes are not boils or tumors. Lymph nodes are part of the lymph system. They are present in your body all the time. We only notice and pay attention to them when they get swollen and/or tender. This usually indicates some sort of infection. The pain in your foot needs to checked out by your doctor, as do the other lumps. The underarm ones could be a result of shaving, might be ingrown hairs, or something equally simple like an allergic reaction to your antiperspirant or deodorant, but because it could be more serious, but you really need to get them checked out. You have more than one, and both sides of your body are involved. This means you could have a systemic infection or another underlying health problem going on. See your doctor and make sure you discuss both problems, they could be related but either way, you need to get to the bottom of it.
