Hi welcome to Health care magic forum.
Thanks for choosing H.C.M.F.
Actually you have two diseases, A.D.H.D you are facing since long, so the thing you are suffering now is entirely different, and should be treated now. it appears to be the renal colic
due to urinary tract infection
or uro lithiasis.
I advise you to consult an urol
ogist for diagnosis and treatment. You may need to have M.R.I.of abdomen besides other routine tests for confermation.
wishing for a complete recovery.
