Reactive Arthritis. These medicines.

Hi Doctor, I'm a 23 year old female. Weighing 65kgs. In August this year I had fallen sick with fever and chills and after doing blood test my platelets were low. My malaria and dengue test were negative. However the doctor assumed that it's malaria and she gave me malaria medicine for 3 days. After taking those medicine I fell very sick. My feet and hands started swelling and I was unable to walk. I went to some other doctor and he said that I'm suffering from Reactive Arthritis. I'm currently on medication for the same since the last 1 month. Yesterday I took my vaccination so I skipped my 1 dose of medicine. Today my feet and hands have swelled up again and I'm having difficulty in walking. Please suggest the best solution for Reactive Arthritis and how long will I have to take these medicines. Thank you!
