Ok. I'll try. You came in on my site and I am in partial experiencing what you are having now. First hand I see so much going on with you and I would not give up on finding a solution. Never give up. Have you heard of Stem Cell replacement ?? Tony Richards the motivational speaker, nationwide presenter, had this done and he swears by it. Your insurance may not cover it ?? He had difficulty moving about. Was focused on his legs and spine. Check online as to what he did to improve his life and his speaking presentations. Other than that...............this is something that is based on Neuropathy, perhaps ?? Many Doctor's would like to view your dilemma. Hope you have adequate insurance ?? Don't go into a hole on expenses. My feet sometimes lack feeling. Have toe fungus from working in the garden for 25 yrs.. Fungus can inhibit walking. I do my own toenail clippings in order to wear shoes. Had a Spinal Tap in Chicago as a Jr. teen. Found nothing for me to worry about. Had a bad fall in December, 2019. Over waxed floor in a restaurant and I did the splits. Never have my legs done that. Was not wearing heels, but 1 in. heel sole. Turns out a injured "ham string". Pelvic bone moved out of socket as well. Many football players have ham string tears. Because I have arthritis, this recent injury has come back to limit my painless walking, stooping, kneeling or simply trying to stand after down on the ground. I have learned to do a spider lift by moving my hands to prop me up closer to my feet (hence a spider formation). Takes a lot of strength in one's arms to lift your body up. Painful, yet I dread falling flat on the ground. If you are gaining more weight..................this does not help at all. You need a lot of strength to get your body to cooperate. Extra pounds makes that difficult. Crawl towards a door frame, chair. object hard enough to carry you to an upright position.
