Hi
Welcome to the MedHelp forum!
If you have multiple swollen glands in neck and in armpit along with pain in chest and shoulder, then you should immediately consult a doctor, especially since you are pregnant. It could be local infection, may not be a lymph node bit a boil or abscess or there may be abscess in breast or even a lump in breast that needs to be investigated.
Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
swollen lymph nodes are usually a sign of infection and weakened immune system.It could be anything so its best to go to your doctor and be examined.
