We Were At Hunting Island SC On Vacation. I Woke

We were at Hunting Island SC on vacation. I woke one morning about 5 days ago with extreme vertigo when I sat up in bed. It caused me to plop back instantly in bed. It took me a while to recover, but was OK during the day. Next morning same thing. My audiologist and i emailed, and she said to perform the Epley manuever. It sounded like misplaced crystals in my cochlea. I also had two swollen bites on my side. I don't know what they were from, but have found and removed two ticks since then. Saturday morning it took and hour and a quarter to get "normal." I saw my family physician PA today, and she prescribed valium for the symptoms, and Allegra, believing it is a hold-over from a chest cold I had a weed before this started. Thoughts?
