D-bug,
I think Lenneth is just about spot-on. My wife had been having strong, nearly debilitating, occasional (once or twice a month) headaches for the last 2-3 years. We associated it with a prior shoulder surgery. They were on the back side of her head, and mostly on the side the shoulder was operated on. She finally decide that the headache pills were just not doing any good. While they would ease the headache, everything else seemed to go crappy. A different doctor gave her an antibiotic, for----sinusitis! Working great so far. For the last 4 months. He explained that there is a sinus cavity that goes well back around into our heads,(news to me) and that she could be having problems there. He gave her Cephalexin, 500mg. she takes 3/day, 10 days on and then 10 days off. I've taken it before, for a skin rash that was due to an allergy, and neither of us has had any problems with it. Might ask your doc about it. I forget, but I think he called it a "P sinus", or something like that. It's been a blessing for her.
Who hasn't had a back problem? Been plagued with them most of my adult life. Biggest part of my problems has been from poor muscle strength right in the area you describe. But, it's not just the poor muscles, it's a lot in how you use them. I've lifted some heavy stuff, and it has usually been small light things that screwed me over. Picked up an empty 5# toolbox once. that cost me a month of therapy. Same for a fist-pump I made at a bad call in a football game, sitting on my couch!! Like you, I've had times when I just could barely move. Remember a time waiting for my wife to get home to take me to the ER, and I had to crawl down the hall to the bathroom. Not fun at all. I'm sure you've heard about repetitive-motion injuries? Many companies, including the one I used to work at, are quite into it, and go to lengths to make sure employees rotate between jobs in order to stave them off. Ergonomics do have their place. Get the therapy, and learn the lower back strengthening exercises. And avoid doing too much of one thing, even if it seems you're not working that hard. After so many episodes over the years, I finally learned that the best thing for me to do, was get the meds, and get right back in and work through it. I've been known to spend 2 weeks working with a sprained back, taking Meperidine to make it possible. Beats the hell out of laying in bed waiting for it to straighten itself out. That won't work for everyone, though. Having had 40+ kidney stones, I've developed a pretty high tolerance for pain-killers. I keep some around just for those occasions. Odd, since I retired 2 years ago, Haven't had one bit of back trouble. Still do lots of lifting at home, but I think the lack of stress has been a factor. Nice to be able to contemplate a job, and say, "well , that looks like a job for tomorrow." Take care!! Patti
