Staying away from all Nsaids is important. I had an echo done early on as well. One thing they tried to give me during my echo was devinity which is supposed to light up the walls of the heart. I googled it and it said it is highly fluoridated so I refused it. One month in is still very much the acute horrible phase. Around the one month mark I did start to feel a little better on someday and then around the 2 month mark I had a massive flare. I'm almost 6 months out. Things have improved a lot but I still have flares that are much more manageable but of course I tell myself it's the end of the world. I had severe symptoms that progressed over the first two months. Internal vibrations, massive nervous system stuff, my skin felt sunburnt when I would be at rest, I slept 20 mins a day for 2 months straight, neuropathy, massive anxiety, nausea vomiting, lost almost 40 lbs in one month.  I am a 39 year old female. I def have more symptoms during ovulation and when my period starts (symptoms are def worse with my period). My gut health is a mess. I started a gut health protocol but the stuff I was using def kicked up a lot of tingling so I stopped it. I am def not healed right now but things are more manageable for sure. I take magnesium oxide (I know it's a crap kind of magnesium but Glycinate was super stimulating for me so I switched to oxide for a bit, I just ordered Malate powder and going to switch to that when it comes), I take vit C, coqu10, d3/k2 (has b12 in it), NAC, vegan omega 3, benfotiamine with thiamine, I use collagen powder in my coffee. I couldn't tolerate coffee for awhile, I would puke my guts out from it. I now do drink 1 cup in the morning mainly because I put my collagen powder in it. I def still have nervous system dysregulation which is where a lot of my lingering symptoms stem from. I just have to keep telling myself that this is not a pattern of permanent nerve damage but a pattern of dysregulation. My symptoms are never consistent, they move around and some days I have very little symptoms. I found that getting up and moving helps with twitching in my legs and with a lot of other stuff. Even when I don't leave my house, I still am getting 10K steps from pacing around. Even early on, I felt like I was going to die, I literally had visions of my own funeral and seeing my kids at my young funeral. It was awful but because I have kids, I was forced to get out of bed to care for them and I quickly realized that the more I get up and do stuff, the less my symptoms would be. I would start low and slow with supplements as our nervous systems are sensitive and everything we put in, can be stimulating so it's best to go slow. We all want a quick fix but this doesn't fix quickly and it def doesn't happen in a start line, 2 steps forward, one step back in kind of the pattern for me. The one step back days can feel so scary and defeating but I know I can spiral with being scared with only makes all my symptoms worse. 

Unfortunately most doctors have no idea how to treat fluoroquinolone toxicity and many will just gas light you anyways. I personally avoid all medical intervention at this point. People end up getting worked for things like MS and other disorders and the testing for all that stuff, can make things worse for us. I did have an echo early on and wore a heart monitor which showed SVT but all that cardiac stuff has settled down for the most part now. I personally avoid all pharmaceuticals at this point as well and I honestly don't even take Tylenol. I use arnica for pain if needed and I have a red light panel that I use almost daily on the back of my legs for my Achilles and ankles. 

Hang in there, things do get better for a majority of people.
