Nah, just nerves.
I must make sure to not over-use my arm for heavy work or have my arm/elbow closed too long (like gaming, that i dont anymore).
Basically carpal tunnel (but elbow?) but also not really it. Im totally fine as long not overdoing it.
(again my balancing luck that i got minor problems that are begnin and not big ones)
ps : its like Captain tsubasa crippled knee but inside-elbow nerves
