If you have tenosynovitis of the thumb, moxibustion should be applied to the area where the pressure pain is more pronounced, that is, to the entire tendon sheath with the knuckles of the fingers to see where the pressure pain is very severe. The moxibustion site should not only be a localized area with obvious pressure pain, but also look for the same pressure pain points in the forearm and arm, because the best results are achieved through the treatment of the whole meridian or the whole muscle. The time of moxibustion is usually chosen to be about half an hour, and the frequency of moxibustion is chosen to be at night before going to bed and after waking up in the morning, because the thumb cannot move during sleep, so this symptom may be aggravated by sleeping, so the time of moxibustion must be chosen to be at night before going to bed and after waking up in the morning. It is important to combine moxibustion with thumb flexion and extension training and exercise, because only by combining flexion and extension training and exercise can tendon adhesions be prevented. If the thumb tendonitis has become very serious, such as the appearance of trigger finger, the finger down can not go up or finger up can not go down, may require small acupuncture or surgery for treatment, the effect of moxibustion is not particularly good.
