Is random rash-like swelling on parts of your body coupled with back pains and joint aches and cold sweats all malaria symptom? If so, what is the parasite type and the cure?
Rashes are not usually associated with malaria infection; the symptoms you describe are however consistent with several other infections, some of which can be quite serious, such as dengue fever. You should go to your doctor or a hospital to have a blood test which can assist in diagnosing you.
For future reference, if you did have malaria, you would still probably need to have a blood test to determine which species of malaria you had, and therefore what kind of treatment would be appropriate.
