Hi. I've lichen planus for about 3-4 months now. I've used prescribed corticosteroids before for about 2 weeks but the rash appeared again. So my doctor prescribed methylprednisolone for a month. And my dosage has completed two days back. Since then I'm not really feeling well. My head feels heavy, I get stomach cramps and my body aches everywhere. I'm feeling really irritated. I have nausea too and lost my appetite. I've slept all day yesterday. Also I have pcod and my period started about a week ago after 3 months. Could that be the reason? I've never had these symptoms during my period before so I'm concerned.
