Hello Sir,
Not knowing any details just offering ideas. (I get some back pain now and again but I don't go through the riggers of work you do now. (Me taking off 40 pounds several years ago has added years it seems to less pain and a lot of other areas.) I used to mow a little over an acre regularly. Do you wear a back brace/support while you are mowing? I found that stopped a lot of my agony. Now after doing some work and I feel my back tensing up I take a 500mg Tylenol. I have Ibuprofen but do not use that for my back pain. The Tylenol works to stop the agonizing pain though it doesn't stop it all. I have been blessed in that I usually only have to take a couple Tylenols a week and one or two Ibuprofen 400MG. Besides my cholesterol medicine (Most of that is hereditary as my cholesterol now stays at 150.) and the different vitamins I take, Oh, I do take an 81MG aspirin a day as prescribed by my cardiologist. I am thankful.
My darling and I just got back from running around town hitting the markets. I am studying for a certification and also for some critical items I have to address this week at work. Drinking a nice light cup of coffee and on my computer...
I will of course bother and pester all throughout the rest of this day...
Oh, God Bless you all and may God full-fill your desires in him. May you also all seek God in all you do and let him guide your path through your life.
