Hi, I'm 24 and had botox in my calfs and hamstrings at about 15.
I only had one treatment so it wore off after a few months, but it did really help, especially with hamstrings.
after the injections I had lots of physio, and wore gaiters both over night and at times during the day to stretch my hamstrings. I still wear the gaiters overnight and to help with physio now, I find them really helpful, especially if I have been very active and have over done things - which is pretty much all the time!!! Gaiters do take a bit of getting used to at first, and I find that when I've been wearing them for a bit, I have to keep adjusting them as the muscle lengthens. I have been wearing them regularly since about age 5, so actually find it easier to sleep with them on as they do help to reduce the twitchyness I often get at night.

hope this helps
