Hi there ~
I understand your concerns. I believe that you have got yourself treated for
scabies. However you are not having good wound care. I also believe that you should not be doing anything including
masturbation if it is going to come in the way of
wound healing. If you wait for a while you will see good results in your wound becoming better and you can involve in any kind of sexual activities at that time. I also think you need to be examined for the
rash as it seems to me to be an infection of
HSV, that needs medical attention. I hope you consult a qualified doctor.
I hope this helps. Take care and have a lovely day!
