After 7 Years Of Dealing With An Unknown-cause Chronic Illness,

After 7 years of dealing with an unknown-cause chronic illness, one practitioner decided to test me for Rocky Mountain Spotted Fever (with many other tests). This one came back. However, in all the research I've scanned today, I cannot find chronic cases. I did have a tick bite about 6 weeks before the onset of my symptoms. Just pain at the location and no rash of any kind. In fact, we did not even consider it a connection until 1 year into the illness itself. The Lyme test done at that time was inconclusive. So, are there cases of chronic SMSF?
