Thank you so much for your appreciation. As a physician , it is my duty to help a patient in any way I can. You are right about the non exposure of viruses during lock down, because kids didn't have the opportunity to develop any immunity to them, and hence, the flu is more severe than before. I'll definitely appreciate an update, and I hope everything will turn out alright.Different physician, but I am not concerned about the leg pain. The lymph nodes need to be investigated at some point soon, but not necessarily tonight. You relate reassuring characteristics about them.The big tell for leg pain is whether they want them rubbed or not. Pathologic leg pains don't get better with touch, and kids flinch away: tumors, fractures, arthritis, osteomyelitic infection, chronic inflammation, all of that is not something that gets better with being rubbed. I don't think I've ever seen something worrisome in the legs causing pain that was better with rubbing.
He was home for most of the covid lockdown years (we were in California and very restricted), so he was never sick or exposed to immune stressors for over two years. It seems like since he started daycare in late 2021 it's been nonstop illness. We've had head colds, stomach viruses, covid, flu, roseola, hand foot mouth, etc, you name it. Would this onslaught of viruses cause lymphadenopathy? Could it cause unexplained vomiting too? The vomiting occurred without fever and far enough from the stomach viruses and roseola to not be linked, I think.We decided to skip the ER and will see his pediatrician this week. I'll ask about the spleen/mono and push for more tests to explain the swelling nodes. Thank you so much for at least putting me at ease regarding worst case scenarios. Let me know if you'd like an update after we get results. I have no idea why you were so helpful to an internet stranger, but I sure do appreciate it!
