My son is 22 years old, he is having red rashes in all over the body and having fever also having joints pain, we go for blood test and urine test but all is normal in test report even blood platelets is 141000, we have shown to the doctor, he told that wait for 2 days he might having dengue and wrote medicine ZATHRIN, DOLO, ZYLERA for 2 days course, so after 2 dose his rashes has gone, and no fever, but still joint pain is there. So give me the suggestion what to do.
