Hyperhidrosis of a residual limb after amputation is one of the most common reasons for impaired prosthesis use and quality of life and affects 30-50% of all amputees causing skin irritation in about 25%. Thus the probability of residual limb pain increases in addition to an increased likelihood of phantom pain due to shorter duration of prothesis use. Development of both types of pain was studied following treatment of hyperhidrosis in 9 amputees. ⋯ Residual limb pain improved 3 months after intracutaneous, low-dose BTX-B in a trial with 9 patients and also phantom pain by tendency. Sweating of the residual limb was significantly reduced, probably thereby improving the duration of prothesis use. Larger studies should confirm these findings and conclusions.

Randomized Controlled Trial Comparative Study
[Long-term effects of interventional treatment on chronic pain of the musculoskeletal system. Retrospective outcome study of repeated in-patient treatment].
Interventional procedures are frequently used for treatment of musculoskeletal pain syndromes but current scientific evidence does not show successful outcome in chronic cases. In this study the effect of repeated interventional treatment on the long-term outcome of patients with chronic musculoskeletal pain was examined. ⋯ Repeated treatment cycles of interventional pain therapy did not lead to an improvement in the treated pain syndromes and in the long term the pain syndromes deteriorated further. It seems likely that the interventional approach promoted this adverse development but the data of this study are not sufficient to conclusively prove this thesis.
