Has anyone had a tummy tuck and is now having things go wrong years later?

Hello! I had my tummy tuck Feburary 26th 2015 and healed beautifully from that surgery. March 2019 I experienced my first muscle spasm in my rectus abdominis muscle and ever since then my stomach muscles feel tight whenever I speak. I also developed hypersensitivity along with numbness and muscle twitching along the rectus abdominal muscle. I had no issues after healing from my tummy tuck except for a little loss of sensation below my belly button. I went to a gastroenterologist and had an endoscopy and colonoscopy done...all was well. I also had two ultrasounds and MRI done, which showed nothing wrong. I had a neurologist appointment recently and was told that I have nothing wrong with me neurologically. I thought I had MS or ALS. The neurologist strongly believes that it has something to do with my tummy tuck surgery. I was incredulous! All that time I was thinking that something was seriously wrong with me. Now I have to find a plastic surgeon who would be willing to take on my case. I am a 52 years old with 3 children...which is why I had the surgery. I've always been super fit and petite.
