### Patient: Doctor, I have been experiencing pain and cramps in my legs while walking for some time now. I also noticed some numbness and tingling sensation in my feet. Can you tell me what's wrong and what medications I need to take?
### Doctor: Based on your symptoms, it appears that you are suffering from peripheral arterial disease. You will need to take medications such as Clopidogrel (Plavix), Isosorbide, Cilostazol, Pentoxifylline, and Becaplermin Topical. These medications can help relieve your symptoms and improve blood flow to your legs. Additionally, you may also need to use Collagenase Topical, Silver Sulfadiazine Topical, Petrolatum Topical, and Calcium Acetate to prevent and treat skin ulcers that may occur as a result of PAD.
