Son's been having painful urination. Dr. Hasn't called back w/ urine analysis which was done some time ago. Home strip showed ph. On med for adhd.

Probably unrelated. You don't say what medication your son is taking, but stimulants are not commonly associated with painful urination, nor are the nonstimulants such as strattera (atomoxetine) or intuniv. If he's been on the medication for more than a few weeks, it's highly unlikely that the medications are related. Sorry the doctor has not called; perhaps call the office and see if you can get results--or take him back in.
As above. Usually th dr. Office calls if something wrong. However, assuming something is wrong whis physician u can call and enquire about the result.
