You can’t be serious about going back to UK for medical attention, you’ll wait 3 weeks for a GP appointment, assuming you can get through on the phone!! Then you’ll jump through hoops seeing a variety of specialists, starting with the least expensive option, then if you need surgery you’ll probably wait 3 years, after which you’ll be discharged after a day and left to fend for yourself no matter how incapacitated you are!! Forget it, stay here!! Go back there, dead within a year!!
