Thanks for your question on Healthcare Magic. I can understand your concern. You are taking oral corticosteroid (medrol). This drug is likely to cause side effects similar to your symptoms. Oral steroids can cause hot flushes, headache, mood swings, restlessness, tachycardia etc. So better to consult stop this drug (medrol). Once you stop it, your all symptoms will mostly gone by its own. Drink plenty of fluids orally and keep your self hydrated. Avoid stress and tension, be relax and calm. Don t worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
