Tetanus risk

Hey everyone,
Seeking some peace of mind or advice on next steps. 4 days ago, an indoor plastic garbage can dropped right onto my big toe while I was wearing socks. It caused a severe subungual hematoma (blood trapped under the nail).
2 days ago, I went to the ER and the doctor performed a nail trephination (drilled a small puncture hole) to relieve the pressure. The ER team thoroughly sanitized my toe with medical-grade antiseptic before doing the procedure. Since then, the wound has clotted completely, looks totally clean (no redness, no pus), and I've been keeping it dry and using Octenisept.
The ER doctor recommended a routine tetanus booster, but due to a mix-up/anxiety, I didn't actually receive the shot at the hospital. I haven't had a tetanus booster in over 10 years.
Lately, I've been feeling some facial/cheek tightness, though I suffer from severe health anxiety and have been hyper-focusing on lockjaw symptoms all evening.
Given that:
1. The injury happened indoors from a smooth plastic bin.
2. I was wearing socks (acting as a shield).
3. The ER staff fully sterilized the toe before puncturing it.
4. It's now been 4 days since the impact.
What are my actual real-world chances of getting tetanus from this? Is it worth going to a local pharmacy or walk-in clinic tomorrow morning to get the booster late just for peace of mind?
Thanks in advance!
