Feel like I've run a marathon just standing

Just some background. I was diagnosed with lupus a year ago, late onset. Fibromyalgia about 5 years ago. Mindy disease 2 years ago. My kidneys have gone down to 30%. 2 failed back surgeries. Spinal stenosis. Arthritis in my back, all my small joints and hips. Need some advice. My lupus is kicking my butt and I think my fibro is also at work. Both legs from hips to feet feel like I've run a mile just walking to the bathroom. It doesn't feel like the arthritis as much as the nerves. My nerves feel like thier on fire. I used to run track and I swear it feels just like when I finished running. Could this be my fibro? My legs also feel like there is electrical charges going down my them and arms. It may sound strange but for the last 2 weeks I've had to do everything in 10 (of less) minute increments. The only reason I'm leaving my chair is to take out the dogs. If I get a shower I feel like I've done some great feat. I've lost eight pounds in a week because I can't eat. I had spinal injections a few weeks ago. This is the first time in 15 years they don't seem to be working. I would like to go see the doc and get a prednisone shot, but the effort is too great. My husband doesn't understand my reasoning. Anyway sorry for the rant. Has anyone experienced this exhaustion in your legs, the burning and electric like shooting down legs and arm. Is this the lupus, the fibro or maybe both? Also how do you manage to get important things accomplished? My house can almost be labeled a disaster area. There are only 3 people living here, but right now it looks like a dozen. I need any advice you have. Thank You all in advance. God Bless You and keep You in His hands.

I have nerve damage as a result of lupus attacking my brain and nervous system at which time my diagnosis was changed to Neuropsychiatric systemic lupus erythematosus NPSLE. For me it began with numbness and electrical shocks and nerve pain in my face, then progressed down my right shoulder and arm. It became so bad that the injections given by my pain management doctor no longer worked, you can only receive a certain number a year so increasing them was not an option. My doctors got together and we decided that my best option was to try a nerve stimulator, I had that placed September 2017. The stimulator has helped tremendously, I not had to have an injection for nerve pain since.

Are you under the care of a pain management doctor? If so, you might speak with him or her and your rheumatologist on what next steps can be taken if the injections are no longer helping.

Prayers to you as I know how excruciating nerve pain is, nothing really helps.
