Welcome to HCM,
You are having itching on both feet with rash.
It is more at night.
You can not wear socks and cover bed cover.
With this much history, it seems that you may be having prurigo
or contact allergic dematitis ...
The cause may be clothes,dust,soap,insects or other contactants.
You contact dermatologist
for firm diagnosis and treatment ...
Antihistaminics like levocetirizine
may be taken till relief of itching.Steroids
in tappering dose might be helpful.
Apply mild steroid cream..
Avoid soap bath.
Avoid contacts with wool,soap,dust ...etc
Avoid stress and worries.
You might be alright..
I hope you got my answer.
