The only question I found was about your veins and how tingling in your hands is preventing you from doing usual tasks. In that question you were wondering if it could be a drug allergy and that you had gone to the ER for help. You also mentioned that you ahve a doctor appt. in a few days, so I hope that doctor was able to address your concerns. If you're still having problems using your hands, it may have nothing to do with a drug allergy but rather something else you hadn't noticed before. If you're primary care doctor can't help you, please find out if you can see a neurologist for the tingling in your hands.
As for the blue, distended veins - I'm not a doctor but if your blood pressure is okay, I can't figure out why the people at the ER would suggest it had to do with increased salt in your diet. Perhaps the antibiotic you are taking has a lot of sodium in it, which would be about the same as having increased salt in your diet. Otherwise, please seek a second opinion if your symptoms do not go away!
