Small sciatica problem help

After reading all the horror stories here, I feel a bit guilty asking for advice. I’ve been dealing with mild sciatica for three days now. I recently started doing trap bar deadlifts (60kg total), which I suspect is the cause, even though the symptoms appeared two days later. I’m experiencing a mild stinging and burning sensation in certain positions along my glute and right leg (mostly the calf). ​I can still walk normally, but I’m looking for suggestions. It feels like a nerve is slightly pinched. Should I stop going to the gym entirely, see a physical therapist, or try something else? I appreciate any help!
