Hello, recently Ive been feeling the weirdest thing that started in my finger and now is kind of in a few different spots. I started feeling like a tiny pulse or like something was crawling under my skin, but not moving anywhere it just stays in that spot and sporadically throughout the day I feel something for a quick second and then it goes away. Now im starting to feel that in other fingers, my foot, and random spots. I am afraid of it being a fungus or parasite. What are some possibilities that this could be?
