Do I have als? So scared

For the last few months I guess you could say I had this muscle stiffness in my wrist forearm and left lower calf. I noticed it whenever I played basketball but it never had any impact on me working out or playing basketball. Recently this stiffness progressed and turned into a weakness above my knee/ upper thigh and my foot has this weird sensation that travels all the way to the tip of my toes. Almost like a tingling sensation but not quite. I also have a slight twitch. I fee fatigued in general but I think that's just depression because of these symptoms. I'm freaking out and scared. Please help. I get slight pain in my big toe as well right under it.
