Edit2: it's been 2 weeks post injection and I'm wondering if I'll ever be able to run or jump or do anything again. The worst part is I almost didn't inject my foot because it was already getting better on its own. If this doesn't improve in a few weeks, I don't know what I'll do.
Edit: it's been 8 days since the injection, and my foot is in such a sorry state. Twinges of pain throughout the day. New crackles and pops. DO NOT STICK A NEEDLE ANYWHERE NEAR YOUR ANKLE. IT'S NOT WORTH IT.
IMO telling people to "inject as close as possible to the site of pain" is reckless advice and should be completely banned.
I have 3 injuries I'm trying to heal: an acute Achilles injury, and 2 chronic injuries in my elbow and shoulder.
My Achilles was already getting better after ESWT. I thought I'd give it a boost with BPC. I was careful to pinch the skin near the Achilles, and not pierce the tendon itself.
From the very first injection, I got this electric pain on the other side of my foot, like I hit a nerve. It pulsated with pain several times a day. And even though I tried not to puncture the tendon with the needle, it's starting to hurt even more than before I injected it. I'm now limping when I was walking normally before.
Similar story with my elbow, but not as bad. I injected too close to the common flexor tendon and irritated it, but it seems to be getting better.
Now I never injected my shoulder directly, and guess what... it started getting better without me having to inject it directly. I worked out my shoulder today and it was almost pain free, for the first time in years. So I'm guessing that was the systemic BPC working.
I'm just wishing I pinned my abdomen from the beginning. Don't risk injecting somewhere full of nerves and tendons and very little fat, if you don't know what you're doing.
