Trigger Trauma

Trigger points - what are they? How do they effect me? what do I do about them?

Trigger points are small areas of tightness within connective tissue. They are typically found in muscles, but can be found just under the skin. Connective tissue is the "soft" support in your body, the tissue that surrounds muscle cells, muscle bundles and muscles. It makes up ligaments and tendons, and gives texture to skin. When it tightens it causes wrinkles superficially, and tight, inflexible muscles and joints in the deeper tissues. Anyway - not all tight spots in your muscles are trigger points. Some of those hard little knots you get in a tight muscle (go ahead, feel the muscles in your neck, I know you've got a few knots) are tender points. The difference between a tender point and trigger point is that when you press a tender point it hurts right where you are pressing, a trigger point will refer pain somewhere else.

It is still pretty unclear how trigger points are formed. Some theories are: micro-trauma (tiny tears) cause the connective tissue to tighten and scar; habitual tightening of the muscle causes them; we all have them latent in our bodies, and some trauma or pain response activates them. I believe it is a combination of these.
So what does all of this have to do with chronic pain? or pelvic pain? Well, if you have trigger points, your pain may not be where you think it is. For instance, I recently saw a patient that came to me with classic TMJ headaches and jaw pain. (TMJ - temporomandibular joint dysfunction, a painful condition of the jaw joint). This particular patient had no clinical findings to justify their pain. The dentist had cleared the bite; an oral surgeon found the jaw to be fine on an MRI, yet the patient still had pain. The patient also complained of toothache pain that was unfounded. We found trigger points in the neck that exactly mimicked the pain she was having. When the trigger points were cleared, the pain disappeared.

There are many trigger points (tp's) that effect pelvic pain syndromes. TP's in the muscles and skin of the abdomen, around the sacrum, in the muscles of the buttock, inner thigh and low back can refer into the pelvic region and pelvic floor. The muscles of the pelvic floor can contain tp's that refer to the bladder, the bowel or the labia. TP's have some pretty predictable referral patterns, but they are not obligated to conform to our textbooks, they can literally refer to any area of the body. Remember, if you have pain in an area caused from a tp, and you tighten the muscles to protect it, you may cause trigger points that refer somewhere else.

So, theoretically, if you develop trigger points in the abdomen after a surgical procedure years ago, that refers pain into your inner thigh muscles, you may not even notice either of these except a vague "gee - that's kind of tight, I should stretch or exercise more." These points refer to your pelvic floor, a place that most of us are completely unaware of unless there is a problem, here the muscles tighten, causing trigger points that refer to your bladder, which makes you think you have to go to the bathroom more often. Frequency may not be a huge problem for a lot of us, but if you are a school teacher, nurse, flight attendant, or any of the other 1,000's of people that can't go to the restroom every hour (or 1/2 hour, or 15 minutes) suddenly this is effecting your lively hood. So you try to hold it. Your pelvic floor tightens more. When you do finally get to go to the bathroom, you strain to urinate (stop that), and eventually you have a full blown, bonafide pelvic floor dysfunction with all of the pain associated. No one knows how it happened; it seems like a sudden onset, because you were functioning fine a couple of months ago.

So what do we do about it? Find a physical therapist. Someone trained in trigger point work, someone experienced with internal trigger point release.
There are a few different methods of trigger point release. They all seem to be pretty effective, and it depends on where your therapist was trained as to which method s/he will use. Some PT's will use a firm sustained pressure on the point for 30 seconds or more. Some will use a gentle pressure - just enough to elicit the referred response and hold for 8-12 seconds, until the referred pain diminishes. Remember these points did not happen over night, and often take several sessions to clear. For trigger points in the pelvic floor muscles, the therapist will work internally, either through the vagina or the rectum. Also, your therapist will work on posture, stretching and relaxation techniques to try to eliminate some of the mechanical problems that aggravate you trigger points.

There aren't a lot of PT's that do this type of work, and sometimes the travel involved is too great of an aggravating factor to justify several visits a week. Even if you are seeing a therapist 2-3 times per week, sometimes that isn't enough. Your therapist may have you work on your trigger points at home. When I send someone home with instructions for self administered trigger point work, I have them use a device to reach the internal trigger points (face it, we aren't built to do this on our own). My new favorite product is called "EZ-Magic" it is made out of medical grade glass, and has a smooth, rounded tip that won't damage the delicate lining of the vagina or rectum. It's important that you work with a therapist that will teach you how to use it properly, and of course, you should never try to self-treat until you discuss it with your health professionals.
