my son is 2 yrs old and is on meds 4 seizures. at about 9 months he sometimes when he cried he would turn blue from holding his breath and 1min later he would pass out it was like that for a while & then he start having seizures, i told the doctors hes having seizures after his breath holding spells & he told me he dealt with kids for a long time & just sounds like the BHS. change doc they said the same thing but said to be safe send him to get a brain scan they came back abnormal. seizures started to get worse & was going to the E.R to much so they hospitalized him and put him on Phenobarbital it helps with the seizures but hes still passing out real ugly its scary his hands and foot twitches and when he comes out of it he is shakey and I cant let him walk . I notice when he cries or or has a BHS his vein in his neck has a lump like a little ball but today when he had the BHS it got to be bigger like pee size. IS this normal I m so scared hes been though enough. hes been on meds for about 4 or five months

Hello, Brain scan being abnormal and child continuing to have seizure episodes is why he has been started on medications and no more simple breath holding spell. The anti-epileptics (medicines for seizures) will take some time to act and during this child might have occasional seizures. Medicines have to administer strictly as it has advised. These medicines have to be continued for three years minimum and four to five months is still the settling time. So occasional episodes do happen, and such episodes have to be followed up with your doctor. The changes you observe on the neck is due to the blood in the neck veins unable to flow due to the contraction of the neck muscles. It's nothing to worry about. You are on the right course. Follow up with your doctor to rule out any complications and give the due time for a child to recover Hope I have answered your query. Let me know if I can assist you further.
