Why do my arms feel so weak?

I have been experiencing asthma symptoms, and my legs and arms feel weak. Are the symptoms linked?

• I know it's a bad cold, allergy and asthma season, but I just want to be sure it's not something unrelated. So pretty much how I've been feeling is...sick. Obviously. My arms and legs feel weak, kinda "noodley". Sorta like my legs could give out. My head feels off, like I can't focus, or I feel a tad disoriented. The head thing is hard to describe, and I know I'm not doing a good job, I'm sorry. It's not a heavy feeling, like with a cold. Almost a light feeling. I've also been having chest pressure and I feel like I can't get a deep, satisfying breath. That part sounds like asthma, I know. I've also been feeling nausea lately... I don't know what to make of all of these symptoms. I know for a fact some of it is asthma, but I really dunno what to make of the rest of it. Help?

• Answer:

  I have the EXACT same problem. The heaviness/weakness in the legs. I wonder if it is a lack of oxygen getting to the extremities because of the asthma...
