I ve had severe tingling, pins and needles in testicles, buttocks, anus, back of thighs, calfs, an out bottom of feet for more than 2 years now. Last Sept. 2016 L-5 S-1 fusion, with relief at all. Currently going to theraphy which is strenghting core but tingling hasn t subsided at all. All medications from neurologist have done nothing other than make me dizzy, so I ve stopped. Have had two e.m.g. s and post op. M.R.I. s With contrast, but no Dr. yet has given me a diagnosed anything.
