Is this sensory overload?

When people touch me, I feel highly uncomfortable. It disgusts me, I guess. I end up scratching myself, and feel angry, maybe a little restless too I suppose. I physically feel a sort of disgust rise in my throat. Usually it gets better when I change what I’m wearing (for example, if someone touches my arm, I’ll change my shirt), or wash that part of myself.
Just a note, I have OCD. What I’m wondering is if this would count as sensory overload or an obsession/compulsion.
