My son is 6yo.,his weight and height are normals according to his Pediatrician. He is in first grade now. He likes to sing and shout really loud. He had a history of asthma since he was 2mos. old. But he doesn't have medication maintenance for asthma. His asthma was only triggered when he has cough and cold, that's the time I gave him the prescribed Albuterol nebulization. I only noticed the lump in his left neck when he was 5yo. It's only visible when he blew something, sometimes when he talked, and screamed. So,I brought my son to his Pediatrician, according to her, she doesn't have any idea what causes the lump on my son's neck since my son was not displaying any signs of infections like cold or even fever. She said that it wasn't even a goiter. She referred my son to an EENT. The EENT examined my son. According to him,there's nothing to worry about the lump if my son doesn't have any difficulty of breathing, pain in his throat or change in his voice. But I was still in doubt of what the EENT told me. So, I asked him if there could be another way to make sure that the lump is not malignant. So, the EENT ordered an ultrasound of my son's neck. The ultrasound result showed no evidence of lump. Why is this that they could not find it in the ultrasound. The EENT ordered another test, this time CT scan of my son's neck. But i never brought my son for the CT scan yet because they said that he needs to be sleeping while they perform the CT scan. I am really scared, I don't know what to do. They said that the patient should not be having cold and cough at least 2 weeks prior to the procedure because they're going to give him some medication to make him sleep. I am really concerned of my son's lump because i read some articles about Hodgkin's disease. The thing I am also concerned is during night time, my son is sweating even the a.c. is on, he's sweating takes about 30mins.-1hour.
What is this lump on his neck? It is on the left side of the lower part of the neck near the jugular vein. What is the cause of this lump?. Please I need your help. Thank you so much.
