Stinging sensation with Equi

Hey guys. Got a question. Did an injection of Equi in my shoulder and got a stinging/burning sensation afterward especially if I rub that area. Is this abnormal? It has happened to me with Equi before. Anyone know anything about this? . . . . Just to let you know, the Equi is 200mg/cc and is made by Dencall labs. Thanks.

Can anyone help with this?

Never had any sort of discomfort injecting EQ. Maybe you damaged a nerve or ruptured a blood vessel.

I wouldn't worry about it as you won't be able to feel it even happened in a few days.
