I had strep like 10 weeks ago then viral throat infection 3 weeks ago. When I was starting to feel better my dad ended up in ICU so I was there fo 5 or 6 days and I ended up in ER for heart racing that lasted. 6 hours I also had frequent urination and had achy legs. They checked for heart attack but EKG was ok except for racing. Heart rate was 112-120. They gave me potassium and Ativan it didn't make me feel good so I stopped taking it.heart rate went down but I have had it happen again. And don't feel right still. I can't get into my dr for awhile. Do I need blood tests and would a walk in help. Now my throat is hurting again
