Thank you for your query.
With the plethora of issues coming up suddenly and your past medical history I suggest that you should go to the emergency room for a check-up. Because of your history of past renal failure
the following symptoms are disturbing:
1. Disconsistent urination
3. Blurred vision
4. Dry cough
Following a clinical check-up the doctors in the ER would like to get your investigaions done.
I hope I have answered your query to your satisfaction.
Wishing you an early recovery.
Rajiv K Khandelwal
