I have possible bihcets... i've had two surgeries one abd. one knee since. both sites healed very quickly however i had severe skin reactions around sites. now it seems im rejecting sutures at knee surgical site. is this bihcets related?

Not sure: These symptoms are not classic for behcets's where we usually find aphthous type ulcers in the mouth, genetalia, inflammatory eye disease etc. A dermatology evaluation will help clarify this.

Rejection sutures : Behcets may be involved but a dehiscence of a wound is not an uncommon event after a surgery. The wound needs to be seen as soon as possible.
