Hi Sunnydee,
I do wear thick socks also and at times wrap a blanket around my feet, ankles and legs. Especially when I am watching TV at night or just sitting which makes it worse, the cold feeling. But then yet when walking a lot I get like sting and burn feelings in my feet. Don't make sense to me.
I do also get insomnia but I don't know if it is due to dealing with pain issue a lot.
As for as migraines and jaw pain I don't have no problems. Sorry you are dealing with this more issue too.
Trish
