Hello, Thanks for your query. According to your history it looks like swelling compressing your spinal nerves leading to pins and needle sensation in your legs. I will advise you to do to do x ray spine and MRI spine. You may need muscle relaxant with analgesic,and neurotropic medicine. lumbar corset and hot fomentation will give faster relief. Physiotherapy like USG and SWD will give quick relief. Spine exercises done regularly will prevent reccurance of such episodes. If all conservative management fails then operative decompression can be considered I do hope that you have found something helpful and I will be glad to answer any further query. Take care
