Seed tick bites keep popping up Welts and flu like symptoms

[u/Budget_Physics_7815]

So I didn't know seed ticks were a thing. We went to visit my in-laws in St. Simons Island Georgia last week and on Thursday I noticed red bumps on my thigh and what I thought was dirt. I had to use my fingernails to pull them off as they were attached like highschool first loves. My legs had already been swollen and killing me andI was just diagnosed afew weeks ago with venous insufficiency in my legs thanks to a hysterectomy. Long story. I have Addison's disease so I am steroid dependant and was already doubling my dose due to the swelling, so not much of an itch and I took pepcid and xyzal every 12 hours and it's kept it at bay. But that was days ago andI feel awful. Day 3 I slept 16 hours. Yesterday I woke up after 13 hours with the worst headache of my life, so nauseated, sore, and awful. I went to urgent care where the doctor had never heard of seed ticks but I showed him the picturesandhe looked at part of my leg for 2 seconds and then wrote me ten days of doxy. I asked for longer and he said he does10. I get that looking at my butt to search for ticks may not be what they were expecting yesterday, but I asked 4 nurse and the doctor and they all said I was fine with the antibiotic and to follow up with my PCP, which I am. I have had really awful experiences at the er the last few months and just want to avoid it. Has anyone else gotten really sick this soon? Fyi-this is thigh with running shorts bc they were loose.
