Im scared because i've started feeling weak out of the blue!

Other conditions

I'm writing this on Saturday and i first felt weak at Thursday, i felt like my muscles weren't as they should be. They were weaker. I wasn't getting tired faster but it was harder to for example: write and carry things. The only times i had weakness was when i felt sick. It was worse than this but i knew i was sick atleast. So a day after (Friday) my throat got a bit sore but i think it might be due to speaking loudly, i was in school and i probably did get my voice louder and i dont really keep track of that. Would be unusual though.

My muscles feel as if i worked out really hard yesterday or something but i didn't do anything out of the ordinary at Wednesday. Also something i caught and felt was interesting. For some reason in these 3 days my muscles grew quite a bit. My biceps got alot bigger, i could be imagining stuff but i don't recall it being this big and during the cold for them to grow feels really weird. 

Im 16, around 180cm tall and i have 67kg. As of writing this (Saturday) it kind of feels like its getting better. I can write and do regular things i do. But it still feels like my muscles aren't working 100%. Also i do exercise fairly often. Atleast 3 days a week but usually more than 5 days a week. Im seriously scared cause obviously when i first googled it i saw that it could be heart disease, diabetes and many other scary things. Im writing here cause i want to see whats up with me? If i should go to the doctor or not? When i said this to my stepmom she didn't think much of it and just said its probably a cold or something. I wish i could think that way.

It is obviously worrying you - go to your doctor definitely - will probably set your mind at rest.

Alright, ill see how i feel. So far i dont really feel as i felt yesterday. Im starting to think that i just got scared for no reason. I think its just a cold cause im sneezing alot and have a sore throat. Weakness is almost gone.

Ok all of the weakness is gone except one, my right arm, those muscles that move fingers feel weaker. Actually only the one moving my thumb. When i make a fist, i feel weakness/light pain in the center of my wrist.
