Talk to Internal Medicine on Consulting

i have a number of issues which are independently effecting my body i.e. sinus, eczema, borderline overweight etc. I have also suffered from severe dehydration (unknowingly) which resulted in kidney stones, now gone. For that reason and to see that have all of them combined to effect my body silently in a more difficult way or not, i have decided to get a full body check up done. just like how to the kidney thing sprung up on me, i want to know if anything else may silently be happening to me or not. I want to know which doctors can perform such an exam, what will be the complete cost, and the duration of this whole process.
