Good luck with that, my experience in the UK is doctors dont give a damn if you go to them because your sick & want to kick. You praise the Gods if you get a 3.75mg Zopiclone script if you tell them the truth why you need them. Pregabs are so hard to get over here now too if you haven't been on them for ages, you really have to accept the fact you will be ill my friend I'm sad to say, get a bit of weed & ride it out the best you can is my advice.
You really want to walk to the doctors while sick, wait around in a room full of people with possible Covid-19, be seen by a doctor that only vews you as a bloody junkie & is at best 50/50 going to tell you "Get out of here" then walk back to your home?
I wish you the best with it, tbh I'd pick that nasty twitchy leg thing over the horrific issue I have with my arse spraying like a hosepipe every hour tbh, each to their own though I guess.
