When you had your alignment done, the shop should've checked your entire suspension, front and back. And there should've been a warranty to go along with it.
Was there? And was the shop a reputable shop, or some guy in his garage?
What immediately comes to mind is you have a worn lower ball joint or control arm bushing.
Jack your car up in the front and grab each wheel One hand on to, the other on the bottom, and try to rock it up and down, then side to side.
If there'e any play in the wheel, you have a bad ball joint.
Then look under the vehicle to the mounting points of your lower control arm. If the bushing looks squished, or missing, that's your problem.
Next time, only take your car to a well established shop, and ask for a warranty slip, which will cover everything they did.
