No problem Matt. The main risk factors for the development of carpal tunnel syndrome are age, female sex, increased weight (BMI - Body Mass Index) and a square wrist ratio (height/width). Night time symptoms are explained by total body water shift while in the lying down position during sleep with resultant increased carpal tunnel pressure. There are some few cases where "use" can be correlated with carpal tunnel syndrome but they are rare and usually quite traumatic such as high impact, fracture malposition, post surgery with increased pressure, and swelling, massive vibration exposure and the like. In the history of medicine this topic has been very interesting due to massive acceptance of an unproven hypothesis (a doctor said "I think...") and established causal theories that are not supported by scientific research. There are many such examples in medicine. The cholesterol hypothesis comes to mind, but that story is very complicated.

OBTW Matt, heavy use can certainly exacerbate a tendency for carpal tunnel syndrome and make one uncomfortable with out the "use" being the causative mechanism for the underlying syndrome. You're not crazy and I am sure you were uncomfortable.

Luckily there is no risk using BIAB. LOL!! Now back to our scheduled programming. Gosh I hope I didn't bore the pants off everybody....
