If your dog has an ear infection it definitely could cause his eyes to be swollen. Infections can travel if not treated.
The most common cause for a swollen lymph node in a child is an infection in the draining area. It need not necessarily be in the throat. Infection over the scalp can also cause this. However if it does not promptly respond to treatment other causes have to be considered.
Kidney stones could cause this. An infection could also cause continuous pain.
You might have a swollen ear after a cold because you have an ear infection. You might also have swollen lymph nodes that make the ear appear swollen.
Swollen lymph nodes are generally painful. Swelling of the lymph nodes throughout your body may indicate an infection. Also, it could be indicative of an immune disorder. Either way, the swelling will cause an inflammatory reaction and will thus affect the nerves in the area by the pressure.
Tender and swollen spots on the head could be from scalp issues. If the hair follicles are irritated, this can also cause tender spots.
You should get in to the doctor as soon as possible if it has not resolved in 30 minutes. Also, it could be an infection.
Sounds like you have an infection. Lymphatic system works similar to the circulation (blood) system, except it only goes one way, whilst the circulation has 2 way traffics (artery and vein). When the lymph swollen it could be caused by infection or tumor/cancer (lymphoma).
There are a number of things that could cause chills if you have no infection including a cool draft. You may also get chills from having low iron levels in the blood.
Fluid retention caused by excess salt intake can cause swollen ankles and a swollen neck. Usually, a swollen neck is caused by swollen lymph nodes which are caused by an infection of some type but since your ankles are swollen also I would suspect fluid retention. Try severely limiting your intake of salt. Do not just eliminate white table salt. Also eliminate salt from processed meats and snacks.
A UTI can cause a foul odor; and antibiotics will cure the infection.
The cause of swollen glands in the neck and under the arms might be due the affected lymphnodes. The swelling of the neck can also occur when there is overworking of thyroid galnd ending in goitre.
Cellular damage and genetic factors influence the formation of cancer. Swollen lymph nodes may be a reaction to cancer, or it may be a reaction to an infection. Also, rarely, lymph nodes can get infected themselves, though a swollen lymph node generally means an immune system response to another condition. A lymph node that becomes swollen often should be checked by a doctor, as it might be an infection that your body is having difficulty eliminating.
