I had quite a few of the same issues.
It could be a slight blockage from the healing joint, perhaps still swollen. Possibly a foreign body from the surgery. The start of a Urethral stricture caused by the joint. I may be a simple UTI.
I had all the above in the first few weeks post surgery and my urine was very smelly. Flow was very erratic.
Get it checked out.
Thanks Chris
