Hi Squiggle,
If your doc said tendonitis in your ankles, and if you were squatting down while gardening, that sounds like tendonitis. What I meant was, hormones don't cause tendonitis, activity does. The first treatment is usually anti-inflamatory meds like Ibuprofen. If that doesn't help, you can go to physical therapy where they might do ultrasound, stretching, massage, and exercises with you. You can also get a cortisone shot to bring down the inflamation quickly. I have to do stretches and exercises for my arms every day.
If I were you, I would really try to rest if you can. The more you use the tendons, the more risk there is of re-straining them. Can you hire a babysitter to take care of the kids for a few hours each day? Think about how you might manage and change your routine if you were in bed with a broken leg, and then do that.
The time to take care of yourself is NOW! I say this because I've had tendonitis in my arms for several years, and the pain and limited activity is absolutely no fun! If you don't take good care of it and allow healing while it is acute (right now, if it just happened), then it can become chronic. Believe me, you don't want it to become chronic!
How long does it last? If you take care of it, maybe several weeks. If you don't, then maybe years. I got mine the first time due to an injured tendon from a blood draw in my arm (bad nurse!). The second time it was because I was using a spray bottle to spray laundry stain remover on my husband's jeans, which were very dirty. Silly, but that did it!
Let us know how it goes for you! Nice to meet you too!
