There was a discount as an open event, so I got the cheapest domestic product, 200 units of calf Botox. I don't remember the name... I think they took care in giving me the injection. My legs are thicker in my calves than my thighs, and my calf area was constantly hurting. For over 10 years, there was no change even when I massaged my calf area with a foam roller or my knee, but once I got Botox, it was effective right away. After 1 day, the pain in my calf was reduced, and it is now the 2nd week. The line has been cleared. I was scared because there was a side effect of not being able to walk or run, but in my case, my calf was a little uncomfortable, but I was careful to use my thigh muscles, so I was fine when I walked.
