My soon to be five year old son is complaining of a hurt arm pit. He feels warm to the touch, but averages a temperature of only 99.3. He is about 4 tall and 33 lbs. He has been overall a very healthy boy, suffering mainly from the common cold now and then. He often wakes up in the night with bad leg and foot cramps which we have been told are normal growing pains. I am concerned because he is not behaving like his normal rambunctious self but really seems to be in pain. He also complained about a headache yesterday which is not normal for him to have. Do you have any recommendations? I appreciate your time.
