Tried to go for a walk... now I'm injured.
42 M. I already have another post here asking for advice. Yesterday I actually had an hour few at work because of maintenance issues. Decided to walk the track next to my work. Nothing crazy...just a 20-30 min walk. I'm all my feet all day but I'm not always moving around as I move from area to area. But 22 min and my feet began absolutely hurting. I had to stop. Spent the rest of the day in pain at work and when I finally got home my left ankle was swollen and the top of the foot as well. Ice and elevation and its just sore today and I'm favoring it. This is just disheartening. I finally force myself to do something that isn't even supposed to be strenuous and it hurt me.
43 M. Any advice on what other cardio is out there for bad knees and feet.
43 M, my health has gotten to the point its no longer funny. The issue that arises is I work long hours usually on my feet. Years of manual labor, congenital flatfoot (born with no arch) and weight gain have lead to significant pain and issues with my feet and knees. I live in a rural area and the nearest gym is an hour away. I also usually don't get home until 8pm or later. Going for a walk is out of the question for the stated reasons, even if there was a place to swim I myself do not know how to swim. Machines are expensive unfortunately. So my question is what other possible cardio options are out there I may be overlooking or missing.
EDIT: I have been looking into machines, space is an issue there unfortunately. Biking outdoors is a no go. I live deep in rural areas and there is no good places to ride a bike.
Surgery in a few days. Why am I nervous...
I haven't had surgery since I was 5 years old. I know apparently cataract surgery super common and has a high rate of success. But i know I tend to build things up in my head. Being out of work, not being able to lift or bend pretty much has me sitting on my ass. My cataract being really thick..... The COST. Just seems to be crashing down on me.
