This patient support community is for discussions relating to undiagnosed symptoms, breathing difficulties, feeling cold, cough, diarrhea, dizziness, fainting, fever, indigestion, itching, nausea, numbness, pain (chronic), paralysis, rash, sweating, swelling, urination problems, and vomiting.
Another consideration, he may be swallowing a lot of phlegm at night...and the rash was from being too warm and sweating...If he has a high amount of phlegm, the lump may be a lymph node that is enlarged....If he is fighting a chronic inflammation of some type (food allergy, soap sensitivity, ear or throat infection) this could be it too...Sorry, I think I may have given more questions than answers...Hope it helps..
