My daughter was diagnosed at a young age (12 y/o) with a Baker Cyst behind her kneecap. (at 3 years old she was diagnosed with Growing Pains with the same exact symptoms… Ridiculous!) From the age of 3 she would wake up, screaming in pain because her leg hurt. It would tear my heart out! She was given Benadryl. When we found out it was a cyst we were told to give her Aleve and let her sleep. There was no conversation about surgery. The Aleve did in fact help her, as long as she had a heating pad on her knee also. She is now 27 and her knee hardly ever hurts her anymore.
