I really sympathise with you, OP, it's so debilitating.
I had a bulging disc on and off for years from heavy lifting of office equipment in my younger days. Always the same left side, pain down left leg, into my calf and foot,
In my early 30s, the gaps between episodes would get shorter and shorter until one day it just went.
I accepted if for a while as I was used to being out of action for a while, but this time I couldn't stand upright, couldn't sleep, couldn't eat, left foot turned inwards.
Long story short: MRI showed the disc had ruptured on the left side, and totally compressed the nerve.
Doctors and consultant made it clear it would not get better on its own, surgery the only option, the longer I left it, the worse the long term damage would be.
I was prescribed tramadol while I waited for surgery.
Surgery was a success - not a single problem since, 15 years later.
Please push for an MRI, OP.
You might have something that will improve by itself, but if not, it's important to know.
