I don't think washing your hands caused this.....
Opana has some kind of blood borne disease that can be causes by injecting it, due to the fillers and ingredients. That sounds pretty serious, and if I were you id go to the hospital immediately.
I've just looked it up, it's called:
Thrombotic thrombocytopenic purpura
However, it's not the exact disease, it's one that's similar in characteristics to it.
If the rash looks like so:

Go to the ER immediately. You will die if you do not.
However, I also found this fantastic post on another forum which may be applicable, it's in the case of a missed shot (didn't hit a vein):
With subcutaneous skin-popping, intramuscular injection, or missed hits everything you inject is left just sitting there, either under the skin or in the fatty tissue, not going anywhere. All the soluble stuff will be absorbed into you bloodstream eventually, but all the insoluble stuff will just sit there, waiting to get infected. It is then down to the white blood cells (leukocytes) of your body's immune system to attack any bacteria and foreign material, in an attempt prevent an infection developing. In terms of infection risk, it's a very high risk method of injection. In reality, with each hit you are risking developing a serious abscessed infection, but this risk is so much higher with non-IV injections.
The symptoms of sepsis are detailed below. One or more of these symptoms may be present:
High fever - increased temperature, dizziness, flushing, sweating, chills, severe shivering or shaking, cold, pale extremities (hands and feet), headache, feeling weak.
Generalised aches and pains, pain in the joints at your wrists, elbows, back, hips, knees, and ankles, abdominal pain and/or vomiting.
Hypotension, increased heart rate and/or respiratory rate, decreased blood pressure.
Less frequent urination, in smaller amounts than usual.
Haemorrhages or rash on skin - may present as a reddish discoloration or small dark red dots throughout the body.
Change in mental state - lethargy, confusion, disorientation and/or agitation.
As sepsis worsens body temperature often falls below normal, and breathing becomes very difficult. The skin may become cool and mottled or blue because blood flow is reduced. Reduced blood flow may cause tissue (including tissue in vital organs), to die, resulting in gangrene. This can lead to limb loss and organ failure. If septic shock develops, blood pressure can remain dangerously low, even despite treatment. Respiratory failure, cardiac failure and organ failure can follow.
Sepsis and septic shock must be treated immediately with intravenous antibiotics - often even before test results confirm the diagnosis. Any delay in antibiotic treatment greatly decreases the patient's chances of survival. People with symptoms of septicemia or septic shock are immediately admitted to an intensive care unit for treatment. Abscesses will be drained, and after administration of antibiotics, surgery may be required to remove dead tissue.
Even with treatment, the risk of death can be as much as 15% for people with sepsis and 40% for people with septic shock.
If you have an abscess (or an infected miss - pretty much the same thing) and you start to display any of the above listed symptoms of serious septic infection, this means that the infection has spread, and you could have septicemia (blood poisoning) or septic shock. If this happens, you must go to the accident and emergency (ER) department of the nearest hospital straight away. If abscesses are left untreated, sepsis and/or toxic shock can cause cellulitis, necrosis of tissue leading to gangrene and limb loss, septicemia, toxic shock, and even death.
