Mild headache and heavyhead since 27days

On 30 july I visited to a water park. On same day and up to 2 august , I was suffering from headache and body ache (probably due to fatigue) but heaviness of head remained .. so I visited to a physician. Physician prescribed me anti allergics , analgesics and antibiotics for 5 days . I did the course for 3 days. Suddenly on 7th August I got accident and dropped from bike.. got general skin abrasion (no history of head injury) I was checked my eye sight that was normal after that I visited to Dr mp khatri he told me of mild migraine  .. I was having his medication for 6 day .. but no relief .. after that I visited to Dr Rp agarwal he also said me of vascular headache he wrote me same salt as dr mp khatri did .. after that I visited to neurophysian he told me of persistent sinusitis and wrote me cefpodoxime .. analgesics and antiallergic ... I has been having his medication so what should I do?
