If I have right knee osteoarthritis, do I have to work out my left side as well?
I was recently asked by a patient why he had to work out both sides of his body in physical therapy if only his right knee hurt. I can understand some of the confusion. After all, if your right shoulder were painful and inflamed and required an injection, the medication would only be put at the site of inflammation -- in your right shoulder. You would not be a candidate for a right and a left shoulder injection! However, physical therapy, for the most part, is much different. I'll explain.
There are two basic components to physical therapy -- passive and active. In the passive component, the therapist may apply ice, heat, ultrasound, electrical stimulation, and other modalities to the painful area. For the most part, these modalities are only placed at the site of injury (there are a few exceptions that are beyond the scope of this blog). So, in this sense, physical therapy is functioning si...
During pre-op testing for my father’s back surgery, the EKG showed a “bundle.” What exactly is a bundle and what does it mean for his health?
The heart's electrical activity normally starts in the heart's natural pacemaker (called the sinoatrial node), which is situated on the upper right chamber of the heart (atrium). From there the electrical impulse travels to the left upper chamber (atrium) and into the atrioventricular (AV) node. Electrical impulses travel through certain cells that are specially designed for the purpose of carrying those impulses. They carry them faster than regular heart muscle cells and are located near one another. When there are many such cells together in a bunch we call this grouping a node. From the AV node the electrical impulse travels down the bundle of His and divides into the right and left bundle branches. When the electrical impulse carrying cells are arranged in a line to carry many impulses together we call this a bundle, if it is ...

What you're describing could be ice pick headaches. You can find more information in Ice Pick Headaches - The Basics . That said, nobody can confirm that via the Internet, so you really should see your doctor about these pains.
Good luck, John Claude Krusz and Teri Robert
