L4L5 Discectomy

weeks after surgery , incision opened and began draining a slight bloody and clear and lt tan liquid , no odor has been going on for a week now have you heard of this happening to someone before and how low should this go on befor healing and stoping. Have been told have a very arthritic spine, plus have osteoarthritis almost everywhere and fibromylagia. Will all this arthritis cause a slowness in healing, getting depressed but great to have the pain and burning gone after surgery
