Thanks for the question.
Yes, you should see doctor for this and that too sooner.Because you might be getting intermittent incomplete torsion of the testis.And a complete torsion can be emergency.
Second thing you might have injured one of the testis with hematoma
would be desired investigation in your case.
You can limit your sexual activities till you see your doctor.
I don't think you should leave this unattended.
Please ask if there are doubts.
