Also posted this in Lung Foundation, but as there are many knowledgable people here maybe I get a new angle of this.
I have strange flareups of breathing problems. They mainly cause blockage/problems when exhaling and take a few weeks until I'm fine again. Then nothing for several months. Asthma meds work well enough.
Together with the first ever occurrence I got a pins and needle feeling at certain body parts. Months later, after it had not improved but even spread to other parts of my body and either knee would give a few times each day when walking each day I was put on B12 shots and the tingling and muscles problems finally got better; tingling almost completely vanished after several months.
Back to the breathing problems: whenever I get a new flareup I also notice that the tingling, especially in the area most affected (a 15cm long spot along my shin) tingles again. It's like: I wake up in the middle of the night and notice at the same time that I have breathing problems and the tingling. I don't think it's hyperventilation as if I do, my hands and feet start to tingle, not this spot on the shin.
Anyone ever heard of something similar? I'm at a loss here. Lung consultant isn't sure there's a connection, but isn't even certain whether I have asthma. I need to come back during the next flareup for some proper testing then.
