Hi Hank, I have been using the Laser TRX for a little over a week now and I was somewhat encouraged after 4-5 days but now the pain is bad again and of course very concerning😔 I’m now at level 2 and decided to keep doing the treatment for a while longer to just not give up and give it more time. Shingles pain is the absolute worst, like a deep electric shock, piercing deep sting and like someone is stabbing you in the back with a butcher knife, just unbearable and it is every single day of my life for 2 1/2 years now! I have not been able to take any meds or drugs to help because I always have a problem or allergic reaction to meds/drugs😳 Anyway, I will keep trying this Laser TRX and praying that it will give me some relief like Jerid🙏 Have you started it yet? So hope you will have good results and pain relief!
