Aqua therapy, Lyme and ankle surgery . . .

Due to ankle surgery and a lyme relapse I haven't been able to exercise very much.
There's a warm therapy pool in town, but it's a long drive (1 1/2 hr. round trip) so I've only gone a few times - it's wonderful!.
I'm so achy and out of shape from the surgery and lyme relapse that I'm thinking of purchasing a 5' deep hot tub for aqua therapy. I found a heated cedar tub with liner that looks like it would be great - http://canhottub.com/total_therapy.html. I've never seen one of these tubs in person. Does anybody have any other suggestions for an above-ground deep heated pool?
I'm wondering what water temperature is best for aqua therapy that will not exasperate lyme?
Thanks!

Same treatment as above - not sure that lyme is gone yet.

I don't have any recommendations on the tub - but it sure sounds good!! I loved warm water therapy when I would have it!

What I really wanted to comment on is your time line (which can be put in your signature line if you wish, through your profile)

I would encourage you to find a doctor that will not rely on just Doxy, otherwise the relapses may become very common for you. Doxy is known to increase the number of round body forms of the Lyme bacteria (sometimes called the cyst form). That is one of the forms that the Lyme bacteria can change into in order to escape being affected by the abx or other treatments we use.

Also, monotherapy (one drug at a time) rarely works after the initial infection phase, so unless your doctor is planning on adding in another abx, you may have to change doctors to get good, effective treatments.
