Haematoma makes sense.
Just after the operation the tissue is vulnerable and a small bleeding under the tissue is possible.
Compare it when you have your hand between the door, it's getting thick filled with blood under the skin.
Most of the times the body will reabsorbing it.
So, no panic dear, no panic, if it's a haematoma it will disappear in some time.
If it's granulation tissue it will become less and disappear when the wounds are completely healed.
Don't be impatient, coz it will take a year till the wounds will be completeted be healed.
After all, a doctor has examed it, studying more than 10 years before becoming a surgeon.
Keep on dilating on a gently way like your Doctor said.
If you are still worried, let another surgeon take a look at it to be sure.
Hope this will help for your worries.
