<human>: Hi there, so I am a 15 year old girl and every where from my knees down to the tops of my feet are aching really badly. I feel as though the pain slowly pulses from harsh to mild over and over again. Sometime the pain is so unbearable that I start to cry! Please help!
<bot>: Hello, As most of the cases reported in this age are due to changes in the physiology. Lack of vitamin D, calcium, hormonal changes, menstrual cycle, etc. I will advise getting your hemoglobin checked once. As low levels of iron can also lead to aches. Post which you can consult a local PCP who can help you with Medications for Calcium, vitamin D3, iron, etc. Do simple exercises at home and exposure to sunlight is a must.  Chat Doctor.
