Getting foot fatigue since a month.

So 40 days back i had completed second round of antibiotics for h pylori. Just after that i went to dubai, i had to walk a lot there. After i came back post 4-5 days of travel it felt like i have some fatigue, i gave it a week but it didn't go away. Also during treatment i had burning in my foot, which eventually went away. But now only problem i have is when i walk it hurts in my food bone, not sore or anything it hurts like as if there's strain happened few days back and its healing, that type of pain. I also had thigh fatigue but it went away 1 week back but this foot pain isn't going, is it because the antibiotics caused any deficiency? I have been avoiding dairy since 2-3 months as per my gastro doctor, I am taking vit d medicine weekly. Also sugar, cbc and lft, thyroid, they're all normal.. Please guide me what to do. How to get rid of it! M I lacking calcium or something? Or is it something else..
