C-section with a spinal tap

Has anyone else felt back pain including tailbone, skin feeling like it’s crawling on your back and loss of feeling in your fingers? I’m almost hitting 3 weeks postpartum and have had no relief. Starting to go a little stir crazy and not being able to enjoy my baby. It makes me so sad to feel like this and only have little energy to breast feed her. Anyone have any tips or tricks to help with these symptoms? I could really use some advice being a new time mommy
