Before kids I was pretty fit, ran 25+miles a week, swam a couple of miles, lifted weights 2 or 3 times. But I had pregnancy complications and couldn't do anything for 8 months then had a a few months recovery after the birth so I was pretty sedentary for a year as I turned 40.
When I tried to get back into running I pulled my patella out and was sidelined for several more months. Doing the exercises for my patella I pulled my shoulder, which didn't fully recover until I was no longer pushing my kids in a buggy. I went back to running when my knee was better but almost immediately pulled a thigh muscle. And so it went on. Before one muscle healed another got pulled. I got myself a physical therapist personal trainer to try and build up slowly, but it kept happening. Not always from deliberate exercise, I've strained shoulder and arm muscles from things like lifting heavy boxes when moving and I pulled a muscle in my leg sitting at a potters wheel. But any time I've tried to get build up I've done something early on, even though I think I'm going slow.
It's been 14 years since I had my kids and I've been injury free for about 14 months of that over all.
I stopped even trying to get fitter about 4 years ago as it didn't seem to be helping, and COVID then made mooching on the couch seem like a good thing! But realistically that was a bad move as my muscles seem to be even weaker now. I currently have a strains in my left forearm, right shoulder and left thigh. Yet I'm scared to try and do anything about it as whenever I do it results in injury quickly.
Has anyone else had this sort of track record for injury and overcome it? Any suggestions for how to build up? or even just how to treat and promote recovery as nowadays, in my mid-50s, pulled muscles seem to take 3 - 6 months to heal.
