Fibromyalgia Issues!

First Issue: I am having a lot of pain in my feet and was wondering if anyone else has this problem w/ fibromyalgia. (Actually, it is in my hands as well ~hurting, ache, feel numb. X-rays taken and hands fine.) If I stand or walk f/ long periods of time, my toes hurt along w/ ball of foot pain. I also have top of foot pain and sometimes feel my shoes are too tight which they're not. I've been to the dr., and an x-ray was taken. Nothing showed. My dr. had me get orthotic inserts to help w/ ball of foot pain. The inserts seem to have helped w/ the ball of foot issue but long periods of walking/ standing continue to be a struggle.
I have tried every brand of shoe I can think of to try. Orthofeet, SAS, Dr. Comfort, Healthy Feet, New Balance, Skechers, Easy Spirit, Aetrex, Clarks, Brooks. They either have too hard a foot bed, too big or too small, too narrow of toe box, arch support way too high, you name it, it's a problem.
I'm sincerely panicking because I have 2 occasions where I need to wear something semi-dressy. Right now, I wear my old Punter Easy Spirit athletic shoes. They are the only shoe I can stand, and they're not the most comfortable at times. I did buy a pair of Taos sandals last year I found very comfortable. Not anymore!!!! Have no idea why!

Second Issue: Does anyone have trouble w/ seating at a restaurant, church, etc...? I am most comfortable in a straight back firm chair with cushioning. If a chair or seating is tilted at the back, it wreaks havoc on my lower back. If the chair is too low, I have trouble getting down to sit. I do carry a cushion I purchased at Wal-Mart f/ chairs that are wooden.

Third Issue: This is SO VERY hard to explain. Does anyone experience a numb-like or pressure feeling in legs, arms, shoulders, or upper back? It is not a tingly feeling. The only way I know to explain in pressure like. It comes and goes and does not hurt. Just annoying.

Last Issue: I find if I do anything out of the norm it sends my body into chaos. I went to the dentist and they had changed chairs. Totally messed w/ my neck for days! That numb-like feeling I explained above. Yesterday, I put a rubber band around a shoe box to return and here we go again w/ that numb feeling in my arms/ hands!

Just helps to release all this wondering to those who know I'm not crazy and do feel these things!
Thank you so much f/ reading

Thank you for your suggestion. I will sure try them.

I don't have feet swelling. At times, I think they may be, but they're not.
I do not have rheum.
Thank you for your thoughts and taking the time to answer.

Thank you. It is the top of my foot along w/ the toes. The pain is when I flex my toes upward or walking. It feels like electricity or stickers to just pain. The pain radiates from the toes to the middle of the foot. If I stand or walk a lot, it causes pain in tips of toes along w/ where the toes meet the foot on the bottom. What type of foot exercises or stretches do you do?
I had to go to the mall today, and it wasn't as painful walking. However, since being home, the pain on top of foot has begun again.
I'm at the end of my rope trying to find shoes. Our utility room has become the "shipping department!"
I can't even stand to wear sandals.
Thank you, again for taking the time to respond to my post.

I will try this! Thank you!

Thank you so much!
