You need to be very careful with steroid spray. Steroids should be used for a short period of time it has a tendency to thin skin or membranes . I would seek a doctor before using any more steroids
I guess another option might be going to an Urgent Care type of place, not using your real name and paying cash to have it looked at. It shouldn't be horribly expensive to have a Dr. just look at it and advise you if it's something serious. I don't know if that would work or if they'd need ID etc.
I have to agree with Danny on this, you need to go see a dr. Don't be afraid to tell your dr what you've been doing, he/she has seen it all before. It'll be okay:) Take care...
