So I'm 33, weigh 175 and am 5'11"... Not over weight but I'm also not in shape. I'm very sedentary and work a desk job, I hardly ever exercise except walking. I used to be very athletic up until about 10 years ago. I figure I should still have some stamina. All I did was garden (bending up and down frequently and crouching), and my legs felt very shaky and weird. The next day they were sore like I ran a marathon. My legs also sometimes feel shaky coming down steps but not going up. I do have sciatica and back pain, pain down my left thigh front and back, and sometimes the right leg. I also get hand clumsiness and thumb tiredness /weakness and my forearms seem to tighten up. I had sex the other night and just from holding myself up on the bed with my arms they were super fatigued after... These are all very odd things and been going on for about 7 months. Sometimes the symptoms are intermittent or come and go. I told my doc and he chalks it up to carpal tunnel and sciatica, but I'm very alarmed. I get twitching as well. I see MS and ALS all over the internet and freak out. There's no way my muscles should tire so easily. I do have health anxiety for years and also generalized anxiety disorder, but this is way more alarming than anything I had before. I feel like I can't do things my grandparents can. It just all seems too neurological to me. This was long as crap, but does anyone have any input? No, Dr did no tests besides questions and align my back... I had a brain MRI about 10 years ago and a spine MRI in 2012 which showed two bulging disks. I had back pain then but not this weakness crap...I'm about to have a nervous breakdown. Thanks.
