Last week I was standing in a shop, standing squarely, facing forward. Feet firmly planted. I had not just gotten up or anything. I had been looking at an object for a few minutes.
Suddenly (and it all happened in about 15-30 seconds) my left leg started side stepping repeatedly, making my stance wider and wider. In those few seconds my brain literally thought "why is my left leg stepping out to the side without me telling it to?". Then I realized what was happening. I was sinking down into my left side. A lady was walking past me and I felt embarrassed almost hitting her and her seeing me in the odd position. I think my leg possibly was trying to support me but it was like it was weak and I slumped over the side and was weak for a moment. Like that side couldn't hold me up. I never fully collapsed but was able to catch myself but it was hard. I didn't feel like I was going to pass out. It was completely different. There was no darkness closing in around me. I've had that feeling once as a child. It was not this. It was like I didn't have command over my body for a moment and it was weak.
Afterwards I was very tired and light headed. I walked back to my car. Drove home (3 minutes away) and when I was about to get out, I reached for the handle of my car and missed it. I went inside. Sat down. When I got up my legs felt heavier a little for the next 20 minutes or so.
Later I decided to go into the hospital and get checked. When he gave me normal routine exam, touch his fingers my nose etc I passed perfectly. They ruled out a stroke (only with blood test and ECG/ also very simple neurological test give: touch your finger to nose, push again my hands/ pull my hands) and the doctor was very adamant that it could be MS and said I would need to get a follow up with a neurologist. They dismissed me having a stroke but I'm not entirely sure that they checked thoroughly. I received no scans (MRIs etc).
My father had small stroke in his early 40s (lived).
