Patients will begin treatment with manual lymphatic drainage in the affected extremity. In this context, while the patients are in the supine hook position, lymph drainage will be applied first to the neck and then to the abdomen. After the stimulation of the central lymph nodes, the lymph circulation will be increased by stimulating the axillary lymph nodes of the relevant region. First, the proximal part will be drained and it will be advanced towards the distal. Drainage will be repeated depending on the edema at the distal forearm-wrist level.

Each evaluation will be repeated 3 times with 10 seconds between measurements, and the data will be recorded by taking the average of the last two measurements (15). The patients will be evaluated by measuring the transverse carpal ligament, radioulnar joint and extensor digitorum muscle with an algometer before and at the end of the treatment. measurements will be recorded in kg/cm2

BCTQ, a self-report measure of CTS, evaluates two domains: 1. The symptom severity scale (BCTQSS) has 11 items that assess pain, paresthesia, and weakness. 2. The functional status scale (BCTQ-FS) evaluates the ability to perform manual activities with 8 items. Each item evaluates the increasing severity of symptoms or difficulty with a high score.

Median motor nerve latency, median motor nerve conduction velocity, compound muscle action potential amplitude will be measured at both levels. Median sensory nerve conduction studies will be performed by antidromic recording with a superficial electrode from the 3rd finger and a stimulus will be given from the wrist 14 cm proximal. Median sensory nerve latency, median sensory nerve conduction velocity and sensory nerve action potential will be calculated for both applications. nerve potentials will be calculated in m/sec
