How To Cure Fluid Patch On The Ruptured Tendon?

I have a semi-severe tear in my ocm tendon on the left side of my neck. It had been three weeks, when I finally got up and around to do some errands. The next day I woke with a quarter-sized fluid patch right over the injury. Is this just another way of healing, since I might have aggrivated the injury during my day in motion? Or is there and imediate need to get the fluid drained? Thank You!
