Pain on Upper Thigh

I waited a full day before taking my 10 month old to the hospital when he broke his leg. His leg wasn't red or swollen so I just thought he was tired because it was close to bed time. The next day he wasn't complaining but he also wasn't getting up to walk so I took him in and found out it was a broken leg. The doctor said it happens all the time with parents that wait because the pain isn't as bad as a sprain or other injuries.
Just the other week we found out a kid on the baseball team had a broken hand but kept playing with it and the original injury was from 2 weeks before he went to the doctors.
Anyway, I'd take him in just to be sure nothing is going on in there.

Hi, Bita:

Could be a pulled ligament or muscle. It will heal itself with time.

I would take him to the doc or ER. My daughter fell and broke her arm when she was 3. Wasn't so much a break, as it was a crack and a bend in the bone. Kids bones are still pretty soft. It could be a hairline or greenstick fracture. Better safe than sorry. Good luck!

Take him to the doctor. He may have a deep bruise, that only requires using ice several times a day, but he may also have a fracture.

Take him to a doctor! If I had a dollar for every story I have heard about mothers not realizing their kids had broken a bone.....He could easily have cracked or chipped the bone.

Definitely take him to the doctor ASAP! You don't want to take any chances.

Please take him to the doctor right away. It could be nothing, but honestly, are you going to let your 4 year old cry and limp around any longer? This is not the place for medical advice.
