It sounds very challenging to have persistent leg pain and difficulty walking despite long-term use of multiple medications. Since Olmy H 40 (a blood pressure medication with diuretic), Defza 6, Nodon 50mg, and Arozan 100mg have not relieved your symptoms over 2 to 3 years, this suggests the need for a thorough medical evaluation to identify the underlying cause.

Possible considerations include:

• Side effects or complications from your current medications, such as muscle weakness or electrolyte imbalances from Olmy H 40.
• Vascular issues like peripheral artery disease, which can cause leg pain and walking difficulty.
• Neurological or musculoskeletal conditions affecting your legs.

Recommended next steps:

• Consult a vascular specialist or neurologist for detailed assessment including physical exam and possibly imaging or nerve studies.
• Review your current medications with your prescribing doctor to check for side effects or interactions.
• Consider blood tests to evaluate kidney function, electrolytes, and muscle enzymes.

If you experience worsening pain, sudden weakness, swelling, or changes in urine color, seek urgent medical attention. Otherwise, scheduling an appointment with a specialist doctor soon is important to address your symptoms effectively.
