Have on occasions suffered terribly with sciatica.On one occasion even presented at A/E 3a.m. as the electric shock like pain was so intense and couldnt reach the toilet in time. I was made to feel a nuisance, given a prescription which couldnt be processed til 9 a.m. Symptoms persisted and following emergancy MRI a slipped disc was diagnosed.Over 2/3 episodes was advised ice packs to reduce inflammation,pillow between knees sleeping,ibuprofen gel,physio,acupuncture,exercises and to keep moving.At beginning lockdown due to over doing the gardening symptoms returned, fortunately not as severe.Ì again used ice pks,pillow,gel,reg walking and looked on line for stretching exercises on a site called Neurosciences,after a few days pain was resolved, although careful in lifting etc continued to maintain movement.Sometimes it is over stretching (cleaning windows/reaching into high cupboards) that triggers the pain.Certainly recommend on line Neuroscience exercises.
