Hi, a week ago I woke up feeling very tired and by the end of the day I was vomiting and had severe diarrhea and nausea. The diarrhea persisted for 5 days along with the nausea. I was told it was the flu by a dr but it could have been gluten as well (severe intolerance and probably celiac). The last two days the stomach upset has gone Away except for nausea and I have swollen lumps (I believe postauricular lymph nodes) behind my ears. The smaller one on my right side is hard and smaller and if I push on it, a fair amount of blood comes out from my ear lobe where my ear is peirced. Both ears were peirced over 8 weeks ago and are not completely healed, however the lobes are not swollen at all and the nodes didnt enlarge until I got sick. The bump on my left side is much larger (3-4x that of the right) and is warm and squishier than the right. The blood coming out is red and is not puss or other fluid. Do I need to see a dr right away and any idea what it could be?
