I've got a long history of knee problems, which is what got me into cycling in the first place. (Low impact.) I've never been to a doctor, since I assumed the knee problems came from a long family history of arthritis. I always figured it was something I'd have to deal with, and I'd keep limber by riding. However, it was getting worse on the 'bent.
The other day, I went for a physical, and the doctor noted the swelling in my knees. I was referred to a specialist, who X-rayed them. As it turns out, there is some wear and tear that is normal for my age, but not major arthritis.
In fact, the doctor suggested that the knee pain is from weak muscle support in the quads and referred me for physical therapy to strengthen quads for riding.
I am in a state of disbelief. I am so happy, since I have seen arthritis literally destroy and cripple so many members of my family. If I had known all these years that it was just a muscular support issue, I'd have been in therapy long ago.
I'm grounded from riding for about 2 weeks , and I get to learn how to fix it as soon as appointments are available. I'm calling tomorrow.
