internal tremor

hi, how y'all doing? 5th month here.

I wanted to talk about a weird symptom I've been dealing with for a while, it's not severe but it's kinda scary.

so, the "internal tremors" happen mainly at night, at the slightest contact of my body with a low temperature the tremors start, anxiety can make them even worse and make them completely uncontrollable, I have no idea what triggers these symptoms, the only way Ik I can contain them comfortably is to be as quiet and peaceful as possible, avoiding moving my body and staying as still as I can.

these tremors greatly worsen the muscle spasms throughout my body, especially in my legs and abdomen, making me restless and anxious.

Also feel my legs burns and my pubic hair stands on end

Does anyone know a way to make them shrink? I would be very grateful
