Sudden weakness in the back.
Hello,
for about 3 months now, the strength in my back has been decreasing. I first noticed it when I wanted to do barbell curls for my biceps. I realized that I could no longer keep my upper body straight.
It has become so bad that I have to tilt my pelvis forward and my back backward in order to stand without it causing me any effort. As soon as I extend my arms in front of my body, a strong feeling of weakness starts and I hunch over. When I lean against something and stretch my upper body backwards, I feel like the vertebrae in the middle of my spine are meeting and causing a pressure pain.
I have been doing fitness sports for almost my entire life, with periods of both longer and shorter breaks. But I have never experienced such sudden decreases in performance before. I have already been to two different hospitals because I felt so weak whenever I stand. Once I was told to try heat therapy and the other time I was told to train my back more. However, I feel like the back muscle from the middle onwards is no longer being activated.
What could this be?
