Left shpulder blade pain going into neck. Swollen lymph nodes under arm.  Pinched nerve?

Pinched Nerves: Swollen lymph nodes in the arm pit is a concern for a physician. It is possible there are two different pathologies or conditions going on here. From the picture, it looks like there is climbing which could explain shoulder blade pain radiating to the neck and might be a pinched nerve.

Swollen lymph node under arm! what can I do?

Monitoring Centers: Lymphatic system absorbs/carries things too big to go into the arteries/veins like bacteria eaten by white cells and digested food. Lymph nodes "taste" the lymph for anything bad like bacteria, viruses, cancers, etc. When it detects a problem, it alerts the immune system and your body reacts. They enlarge in response to the inflammation they create when they react. They shrink when all is well. ...Read more

I stepped on a piece of glass, cut my foot. Didnt go to the doc. Had td shot. Low grade fever, swollen lymph node under arm past week. What's wrong?

Mixed message: You describe a weird situation. Is the cut on the foot red, hot, swollen, tender and getting worse ? No lymph nodes in the groin? Are you coughing, nauseated, burning on urination...Etc.? A foot wound should have local nodes involved. You may have a virus, or something else going on besides the healing foot cut. If you are not getting better, a doc visit is probably a good idea to sort this out. ...Read more

The nodes are high up and adjacent to veins extending to arm.

Family practice : You seem pretty knowledgeable for an 18 yo. Pressing on the lymph node lightly should not cause any harm. Sometimes pressing on boils or pimples will cause further injury but you are being treated with antibiotics so shouldn't be a problem. Always check with your dr if swelling persists. ...Read more
