Ziggen!! GO SAUNA!!! NOW! (It's what you have been looking for!)
But, take it slow and carefuly, 2 minutes sweat, 3 minutes shower in cold or luke cold water, then 2 minutes in the sauna again, 2-3 minutes cool showers, sauna, shower, sauna shower, 10-15 minutes brake, drink lots of water, maybe refill lost minerals too (salt?, copper?, etc)... but don't eat!.. then hit the sauna shower cycle again... until your head nearly can't take it anymore... you feel when you'we had enough..
You can build your self up to longer than 2-3 minutes tolerance in the sauna over time, but be careful.... i nearly had a body crash some time ago, too few minerals left in me i guess.... at that time the saunas felt abnormally hot even after only seconds in there (Temp was the same as always 90c).... so that may be a STOP or WARNING sign..
Anyway.. the sauna type that works best for me... is wet sauna, or i.e.. the steam sauna... steam rooms in comparison is mild.... for me... dry saunas may do the body better, and steam saunas do the head and top body regions best.... FIR saunas, i haven't tried yet... But the steam sauna is the best one to endure in for longer sessions with me.....
After doing this right, you may feel a pressure in your head / brain, like a metal ball inside your head, maybe a little dizzy (don't overdo the saunas), and maybe abit tired, but also rested and most of all RELAXED, and HAPPY, if not scared from beein too dizzy that is....
Anyway if all went right (not too much, not too little sweat), you will have a day in heaven or paradise afterwards!!
Day.2 will be ok... day.3 will give be less than ok and start giving you some metal redistribution around your body..... from there of it will take 3-4 days for me to settle the redistribution pains and muscle stiffnesses, after that i am overall better and with less muscle aches than before i started out!
I suggest eating raw broccoli before and after a sauna to refill lost minerals or to prepare... and maybe even garlic too.... both to loosen merc in the body pre to sauna, and to avoid redistro after sauna..... have not been doing that myself yet..... mixed reasons...
Btw... i'we been doing this with 1 amalgam and some small amalgam patches still in place... This is amongst other things mainly how i detox....
Works wonders!
Saunas... showers.... same thing.. think about it... only saunas is way stronger and lasts longer!
So Ziggen... if showers is what you cling onto for relief, then saunas may be for you! (that is if you can handle the heat and metal mobilisement and whatever sauna "dosages" you choose to test).. As said, you feel when you'we had enough for the day..
I pressured myself to my edge of tolerance some times, it gave results, but i don't recomend you overdo that too often or too close in time...
The body has to be refilled of lost minerals from sweating as said, or else you may crash....
Ziggen.... go try out the saunas... they're in the public swimming pools or fitness studios, atleast in my country... and it's cheap too, at least the first.. not the latter..
Cheers!

And take care!
