Feeling fatigue. Down that time to 37k.

On nov1, 2016 I got high fever 102 it continued for 3-4 days. I had upset stomach,vomiting at that time also. I got my blood , dengue, malaria test. My platelets count was 72k . But no dengue, malaria detected. After 2 days I again had my test done, my platelets raised to 83k. And my condition also improved. Only thing I have is body pain mainly in legs. I didn't test for chikungunya although symptoms were closer to that( source internet). I still have fatigue in legs( always feels like I have came from 10km run). Also I feel weakness in body. And feel difficult to concentrate on my work. Although I am maintaining a balance diet. My concern is whether I should consult a doctor or should I keep on going with my balance diet and everything will be okay after some weeks. Also , my previous history: I had dengue 4 years back my platelets went down that time to 37k.
