It starts under my arms and wraps about midway into my back.. it started about 2 days ago. I can barely put deoderant on or even lift my arms up... its like a huge charlie horse that keeps getting worse. I haven't done anything different... no exercise . I am 20 yrs old. Perfect health. No new matress.. everything is normal except one thing.. me and my fiancé have a brand new house and haven't got a dining table yet and there is a lamp hanging from the ceiling that is suppose to hang over the table... since we don't have one yet I usually walk through that area and walk right under it but I recently almost knocked myself out when I tried to walk under it. Could I be getting taller? I didn't think it was possible for me to grow taller at age 20... could that be why my back hurts.. sorry so long.. thanks for your time.

Try Eating Less Fatty Foods:)

But I don't eat fatty foods... I actually eat pretty healthy.
