My lower back is killing me after a 20min trip. Right above where a belt would sit on my waist. The pain only started in the last 3-4 weeks. I have tried every possible combination of seat position I can think of. I am 5-8" about 140lbs. I have owned my Focus since September of 2014. I dont know if this is a side effect from the seats breaking in or because with the warmer weather I am no longer wearing winter jacket. I have taken multiple 3 hour trips in the prior few months of ownership and never noticed this pain. Advice is much appreciated. Have tried cushion on the seat and rolled up towel on seat back. I am out of ideas. Maybe some of you have a similar issue and perhaps I am missing something obvious. Thanks in advance.
