What Causes Bruising Around The Vagina And Inner Thighs?

I had an abdominal hysterectomy on April 18 2014, they removed all but the ovaries. The incision site is the same as my 2 C-sections (1 emergency d/t placental abruption). Started having bruising on April 21 that turned my thighs & vaginal area black with in a couple of days. On May 3, I started bleeding bright red blood & with in 2 days it was like a normal menstral cycle. I seen the surgeon on May 5, he did a regular pelvic exam & said I had a hematoma draining above the vagina. Nothing to be concerned about, contact him if I get a fever. I continue to have a moderate (severe at times) pain below my incision site & in the creases of thighs (groin area). I went to my regular OB/GYN today, he did his exam & ultrasound. Said I have a 1 1/2 open area above the vagina where the hematoma is draining but the ultrasound showed a 4x3cm area of fluid. He advised me to see the surgeon b/c it needs to be drained ASAP & he started me on Flagyl 500mg BID x & days. I called the surgeons office. They said not to drive up there b/c if they did anything the risk is greater than the benefit, they said to see my OB/GYN again in 2 weeks to see if the area is larger or smaller. Since this appt. today the bleeding has decreased significantly & the pain has increased. I m confused as to why one DR. would say it needs drained ASAP but another says to wait and see. The reason for my hysterectomy is b/c I was having severe right sided abd. pain in Nov. 2013 which a CT showed a 3cm mass in my uterus, went into surgery in Dec. & the DR. said he thought my bladder was involved & sent me 2 1/2 hrs away from home to see a specialist which is the one that performed this last surgery. I was told after surgery that it was a benign polyp, they also removed several cysts. I also found out today that they cut my rectus muscles. Where I live has been very hot & humid so I don t think I would notice if I had a fever or not & besides getting nauseous, feeling tired all the time, having no appetite & overwhelmed with pain, I just have this feeling that something is wrong even though I keep being told by everyone not to worry. Please give me some kind of recommendation as to what I should be doing. I have 2 different doctors orders & I am very confused & very tired of the pain. I am very concerned & would like another opinion. PLEASE help. If I have to pay for this answer then I m sorry but I am the only income for my household of 4 which includes a 3yr old with brain damage & Cerebral Palsy & I have been out of work for 6 weeks already.
