My 7 month old has strange symptoms

[heartbroken10]

My 7 month old has been doin strange things for a while.I've taken her to the doctor and they tell me everything is  fine. She does this thing where she curls up her legs and pulls on her clothes. She doesnt cry it's more like she's pushing or like a moan. She sweats when she's doing this and it seems like she has a big head for her age.I saw this thing on the internet that is called Intussusception (intestinal blockage) and it scared me to think she has this.Its been going on for a while now.Maybe since she had 4 months. If anybody can give me some advice or help I would gladly appreciate it.

She goes to the bathroom fine.It will look like shes constipated but she's not.

Does she have regular poops, that look normal?  If not, is there a possibility it is constipation?  A friend's daughter had intussesception, and it manifested pretty obviously (although it took the doctor a while to diagnose it, there was clearly something wrong.  They were testing her for milk allergy and a whole bunch of other stuff.)  Before I'd be concerned it is that, I would look to the question of how hard her stool is when it does come out, in case it's something simpler like constipation.
