Two puncture wounds

Got bit by some thing last night. It left two little puncture wounds and swelled. Think it was a spider. The venom attacked my muscles. When I was just sitting still it was fine but when I flexed my leg it sent this spasming pain along my leg. Finally I went to bed because there was nothing we could do about it. I did take some pain killers. My mom told me to call her if I had muscle stiffness and spasming. It was around 1 in the morning and my leg was under the blanket and it was warm. I think the warmth was making it hurt worse. My mind was so tired that I just wanted to sleep and I didn't care how it hurt. But the heat was making it send a shocking pulse through the muscles in my left leg. It was tingling and electric spasming, causing my toes to twitch. With my half asleep brain I kept thinking as long as it doesn't really spasm and no muscle stiffness and I kept repeating that but of course I'm practically asleep and I kept forgetting what I was supposed to be remembering. The pain became so bad that my whole body would twitch just to get a respite from the strange pain for a moment. I sent a text to my mom and if she got it and came then good if she didn't then too bad I was too tired to really give a crap about anything. And I knew I had to get up early in the morning for a breakfast. I settled my blanket around me so that the bite part of my leg was not covered by the blanket. The air from my fan was cooling my leg and practically numbing it. It still kept sending out a electric pulse of muscle spasming along my leg. Finally I managed to fall asleep. My mother came and checked up on me once during the night and again in the morning. It seems to be fine but still hurts some.
