Raised eosinophil level and swollen lymph node

[Alexandra84]

I posted last week regarding fatigue for 7 yo DD.
GP appt today, still feel absolutely lost and worried.
Context-DD has had on going fatigue for a year. She also looks so pale and with dark shadows under there eyes at time (we are both very pale naturally, but it's the dark shadows that catch my eye).
Eosinophil levels are 2 10*9 L (Normal range is 0.04-0.4). States this is 20%.
Eosinophil levels back in Jan 23 were 18.1%.
While at GP today, I asked for prints out of records. She also had a raised lymph node back in Jan 23. No one has mentioned or check this again.
Gp said he will refer to haematology. I asked how long this could take and he shrugged his shoulders.
She shows no signs of asthma, allergies etc.
Do I ring and insist that someone tomorrow sees us who can provide a little more insight than a shrug, or do I just ring somewhere like the Nuffield and ask for an appointment?
For context, she is tired, agrees to a sat lunchtime nap etc, but does play and run around with younger brother.
For a bit more back ground detail, all other test were fine and within range.
Husband working away, feeling very overwhelmed at the minute.
Any more insight appreciated.

I think it's reasonable to ask for someone else to go through the history and results with you.

Small lymph nodes are a normal finding in children, if there haven't been any concerning changes in the intervening year from your point of view that is probably a good thing.

High eosinophils suggest that the allergy sensing part of the immune system is on high alert, but if there's no actual history of allergy or related conditions it might not mean anything. I don't know that a haematologist would say more than that. Or do they mean asking for a blood film (looking at cells under the microscope)? This is often added on routinely especially for children's results so may have already been done.

Persistent allergic rhinitis can give dark circles under the eyes, if there's any allergy type symptoms at all you could try an oral antihistamine for a spell of time just to see (eg over the counter).

If there are persistent unexplained symptoms then referral to a paediatrician on NHS seems like a reasonable option, or you could go private at that point and wait less. Sometimes there is no specific answer in the end and the mysterious symptoms resolve themselves just as mysteriously.

But someone who can dedicate time to the story and follow you up may be able to reach firmer conclusions.
