My back from my waste to my shoulder has etchy dry patches but not sore ?

If you shop around there are plenty of styles of handlebar. Might be worth you trying a bar from a dirt bike or some sort of cruiser bike.
Another option could be to tilt your existing bars back a small amount and add a fork stem riser. Sometimes simply raising the handlebar height on the fork top can help.

well notify his doctor with medical concerns not the internet

Diet is a huge contributor. Is there something in excess in your diet or new

It is best to moisturise or soften cuticles before pushing them back and if they have grown long then pushing them back a little at a time is best.

I think it is best to leave the excess for a while unless it is a nuisance, leaving mother nature to heal the damage a little before going further. Be careful of possible infection in what are effectively self-inflicted wounds.

I advise the use of a soothing antiseptic ointment, preferably one with a mild local anaesthetic. In a few days when the soreness has disappeared you will be able to trim the excess as it becomes accessible - a little at a time.

Naturopathic chiropractors differs from person to person. For some it works wonders, for some however it doesn't get that effective.

Talk to a chiropractor about the way you hold on. I discovered (front seat) that lowering your elbows releases tension on your neck and shoulders. I try to ride like that all the time, now, and find I can easily do 3 or 4 times the saddle time I used to. My rear
gets sore way before my neck & shoulders, from that one simple tip.
