I'm not big on sharing my health online but I too got whollopped this spring by a black legged tick (deer tick).
It got me right behind my right knee and I found it the next day but I already had the bullseye and I went to see my Dr.
Anaplasmosis
The bottom half of my right leg hurt internally with the pain one gets as the bones are growing in your teen years, that deep, moan inducing pain.
The issue is that unlike growing pains, Advil and Tylenol didn't touch the pain and I can't take the harder stuff so I suffered for 3 months and walking was pure agony.
I ended up on 2 meds, very powerful and gut wrenchingly hard on the gut. 4 months later, I feel almost 100% and the pain is gone.
My takeaway is to make sure I am wearing my treated clothing and get my wife to peek at my backside when coming in from chores. I never want to repeat this illness.
