I was prescribed nitrofurantoin for a bladder infection but finished the prescription 3 weeks ago. however, i'm still having pain and tingling in my forearms with numbness and muscle weakness in arms and legs. I haven't been feeling well. I have been to 2 er's and my family doctor. Today, I went to see a neurologist. Nobody can find anything wrong;therefore, I'm not getting any relief or help. My family doctor isn't being very helpful. Any help would be appreciated. thank you. I'm desperate.
