Cold feet made worse when i play first person shooters
Interesting ... when i play a computer game that "excites", my feet get cold realy bad too. My feet also get warm laying down/sleeping.
You also have this dandruff issue too .. wonder how these things are interconnected (sitting and stiff fascia around the hip/gut area restricting bloodflow or nerve signaling? so when u play a game that triggers the sympathetic nervous system it is just to much? just a wild idea ...)
I feel there is a issue with the central nervous system and/or neurotransmitters/stresshormones not regulating itself properly.
The causation for this could be alot of things unfortunately ... i am still working on it. It has gotten better overall compared to how it was last year.
Marijuana or alcohol making it better sounds like its "calming" your body out despite of the unresolved stressor.
