this study will be conducted to investigate the therapeutic effect of complete decongestive therapy on carpal tunnel syndrome post-upper limb lymphedema.

lymphedema is a chronic condition characterized by lymphatic vessel ectasia and valve dysfunction, followed by the reflux of lymphatic fluid into the interstitial space. Lymph stasis may lead to a chronic inflammatory process, resulting in adipose tissue differentiation and fibro adipose tissue deposition. One consequence of post-mastectomy lymphedema may be the development of nerve entrapments. One example is median nerve entrapment in the carpal canal, or carpal tunnel syndrome (CTS). many studies assessed the relationship of CTS as a risk factor for developing lymphedema, other studies stated the possibility of lymphedema as a potential contributor to CTS development. Complex decongestive treatment of breast cancer-related lymphoedema is an accepted strategy and is considered as an international standard for treatment. A previous review concluded that complex decongestive therapy has a positive impact on the volume of arm and quality of life in different stages of lymphedema.sixty females will be allocated randomly to two groups; first one will receive decongestive therapy and the second one will receive the routine medical treatment for ten weeks
