Girls, can you help me? I have very bad swelling in my limbs. My hands get numb at night and they feel stiff. In the morning it's hard to bend my arm into a fist. I noticed that I drink more fluids. I go to the bathroom often, but there isn't much urine. The doctor prescribed Kanefron and Neofit tea, and Norvven tablets, and evening foot baths with salt. But something is not helping. My legs hurt, especially in the evening ?
