Hi @pennie, welcome to Connect.
I'm tagging fellow members @wronnie888 @thegoodwife @ejlouboutin16 @predictable @jeancary @alicein_wonderland @beachgal8 @motherrules4 who have talked about LP shunts and/or strokes recently on Connect.

Pennie, are your headaches classified as migraines? Here is more information about symptoms of migraines http://mayocl.in/2bvc4bc, where it states "Sometimes, a migraine with aura may be associated with limb weakness (hemiplegic migraine)."

Have you spoken to your physician about the headaches and weakness in your legs and knees?
