Well, I think it accumulated over time and suddenly went 'nope'. I was doing one arm tricep extentions (cable) and mid rep suddenly felt this pain in my elbow, it wasn't that bad, but it got worse rather fast to the point where it is now. I suspect nerve damage because when I touch my forearm my hand tingles, but idk.
The thing that must have caused it was overuse. I was doing my normal training (chest/triceps every second day), then doing calisthenics at college and training a client at night - I prefer doing a hands on approach with my clients, so some days I would do chest in the morning and chest at night, add in some days where I had shady form I guess it was just too much for the connective tissue. Add in the fact that I was too stubborn to listen to my body.
Can't say for sure though, GP couldn't tell me anything except give me a referall and anti inflammatories
Thanks

I hope I can get it sorted out, I hate not gymming :d
