Can anyone please help with this issue?

My son is 8 yrs old…

For the past year he’s had sore legs on and off and I thought they were growing pains as I had them quite bad at his age.

But they became more regularly so I decided to take him to the doctors about it.

They did a range of movements with him and made us get a full count blood test.

We did all this and they rung about a week or so later asking us to do another blood test which we did and they rung us to get a follow up appointment.

When we went to this doctors visit we were told mu sons eosinophils ( which are infection fighting white blood cells) are high.

First blood test they were 1.2
Second blood test 1.5

The Doctor asked a lot of questions like has he got asthma, allergy etc

He has nothing like that, we got sent to get a xray, stool sample and another blood test.

Xray was normal
Stool sample ruled out parasite infection
And his full blood count eosinophils are now 2.3

We are now being referred to a specialist, but from what I understand this could take awhile.

Other then sore legs, he seems completely healthy, not off his food, no temps etc…

Do you think it’s ok to wait for a specialist?

What’s your opinion on what’s going on?

Have you ever dealt with something like this with your kids?
