SYMPTOMS OF CARPAL TUNNEL PROFESSIONAL

'Locking' of the fingers in a flexed position is usually an indicator of 'trigger digits' - a separate condition which is frequently associated with carpal tunnel syndrome. True rigidity of the fingers, like swelling, is usually an indicator of other diseases, either rheumatological (rheumatoid arthritis, systemic sclerosis), or neurological (dystonia, stiff person syndrome, spasticity of any cause). StiffnessĪ common perception in CTS patients is that the fingers are stiff but when passively flexed by an examiner this is not usually the case. Other swellings which are visible to an observer along with all forms of deformity of the hand joints are usually indicators of other disease processes (some of which may cause secondary CTS).

This is referred to in the American literature as a 'volar hot-dog' and is of uncertain nature. There IS often a modest swelling just above the wrist, over the flexor tendons. Objective examination of the hand and fingers usually fails to reveal any measurable enlargement of either hand or digits and in most cases this feeling of swelling is probably a misinterpretation of the sensations of numbness and clumsiness. Many patients feel that the hand is swollen, or the fingers 'feel like sausages'. It's relationship to carpal tunnel syndrome and exact cause are uncertain. This symptom is described both by untreated and treated patients but seems to be especially noticeable after carpal tunnel surgery. The analogy which patients seem to be making is that of plucking a tight string or suddenly releasing a rubber band. It is a sudden, unpleasant, shock-like sensation in the palm and or fingers, or occasionally spreading into the forearm, usually precipitated by some movement of the hand. 'Twanging'Ī surprising number of patients use this word to describe a sensation experienced in the hand for which there seems to be no entirely satisfactory technical medical term. This is now complete and demonstrated interesting changes in the small nerve fibres which carry pain sensation in carpal tunnel patients.

We have assisted with a research study, based in Oxford and London, the - PiNS Study. The mechanism by which CTS causes pain is poorly understood and patients attending the Canterbury clinic may notice that we ask a lot of questions about it while we try to understand the differences between patients in this respect. It is also the most variable symptom in distribution, sometimes affecting not only the hand and fingers but the arm all the way up to the shoulder. Pain, as a distinct sensation recognisably different to tingling and numbness, undoubtedly occurs in carpal tunnel syndrome and can be an early or late feature. This patient had no measurable function in the median nerve when tested and did not remember how these lesions of the fingertips developed. Occasionally loss of sensation can become so severe that the patient does begin to suffer injuries to the fingertips without noticing - burns being the most common. As with tingling, this symptom should theoretically occur only in the anatomical territory of the median nerve but some patients do seem to experience more widespread numbness. It is rare for a digit to become completely numb in CTS such that no touch, pinprick, pain, burn etc can be felt at all but a perception of loss of sensitivity of the fingertips is common and when persistent suggests more severe nerve impairment. Whereas tingling/paraesthesiae can be thought of as an increase in sensation, this symptom refers to reduced sensation. Patients who get tingling ONLY outside this area probably do not have CTS. The anatomical distribution of the median nerve suggests that this abnormal sensation should be felt only in the thumb, index and middle fingers and the adjacent side of the ring finger but in some patients it appears to spread outside this area. In carpal tunnel syndrome the distinction between tingling and pain can sometimes become blurred, the tingling of CTS sometimes possessing a peculiarly unpleasant character. In ordinary life this sensation is mostly perceived as mildly unpleasant but distinct from 'pain'. This sensation is familiar to most people from the common experience of having a foot 'go to sleep' after sitting in an awkward posture for some time or after hitting the 'funny bone' at the elbow on a door frame.

SYMPTOMS OF CARPAL TUNNEL PROFESSIONAL

The earliest symptoms of CTS are usually tingling / pins and needles, in some combination of the thumb, index, middle and ring fingers which most characteristically wake the patient during the night, usually at about 3:00 am but a variety of other things may be noticed by the patient or medical professional examining the hand.
