What Causes Unusual Movement Under The Skin And Brittleness Of Toe Nail?

About 5 years ago I lived in old Lyme ct. On a lake. My kids n I walked to lake n hung out I walked in the water. On away home I got a blister on my big toe left. A few days later I popped it n lil black dots came out. I told my primary n he said shower in lice med. Come to find out my kids wound up with live. So I treated us all twice once 4 hair and again for body. Come to find out lake (Rogers lake in old Lyme ct) was closed for years. Over weeding, strange this that etc. Never knew when I bought the house just so happened the pharm tech lived there. She never remembered an all clear just stay out signs disappeared. So over 7 years later I did primary s recomend. Spent years thinkin some kind of parasite in my body. Would feel all wound up in a spot then take vinegar bath n get tons of long knotted hair coming out of skin. Now orig big toe nail still thick brittle n if I clip falls off completely. But other hair n under skin movement would only stop for days now symptoms have transferred to other big toe. Same prob started with pain now nail brittle n no longer attached. Itches n tried every athlete foot med cuz symptoms r there n then some. Have consistently lacking energy, still feel like worms or something under my skin as well as teeth breaking n rotting when I have had 3 children & perfect dental health as well as had nose surgery for deviated septom with no complications. Also just lost an uncle to mersa n brother diagnosed with Lyme disease. I have no ins n am in a financial abusive as well as mental n emotional abuse situation. So any clue WTF goin on? Lived with brother n uncle if that helps. Also had a tick in my scull bout 30 years ago but only been dealin with this for bout 7 years
