I don't think you hate riding,you hate the fact you are aging and have to ride to feel better.Maybe time for a new bike or route.Buy 2 bikes and call me in the morning. I really wanted to say a friend of a friend was in alot of pain.He is a former rugby player and now rides to and from work.40 miles a day.He was taking 4 ibuprofin pills a day for years.Went to the doc not feeling well. Took awhile but he found out his kidneys shutdown from too many ibuprofins. So he is off them and drinking water to flush the pills out. So just be careful of overdosing on pain meds even over the counter.See a 15 minute bike ride isnt so bad.
