Hello, I have been having weakness and twitches on the right side of my body for some time now....Sunday morning I had excruciating arm pain before it went away, I fell asleep and when I woke up, it was shaky and twitchy and weak. I can lift and pull, type and write, I'm just wondering what it might be. Another thing is that I have been walking with a limp as well. My grip feels weak. I know it isn't ALS or anything seriouse as it wouldn't be this quick. Im 17 years old and am not active at all. Everything that happens to my body is on the right side. I'm not overweight, I'm about 120 pounds an am 5'6. I smoke an E cigarette and I avoid all types of caffeine or alcoholic beverages. I need to know that i am OKAY. Do you think it is a pulled muscle somehow? Or...problems with my dibilitating anxiety disorder? Please get back to me as soon as possible as to what it might be. Thank you.
