Using a Spa with Fibro

We just recently purchase a spa, I thought it would be great for my tired body and aches and pains. I have used it 3 nights so far. I think it is helping. It certainly helps when I am in the spa, my body feels great. When i go to bed at night I still have the same aches and pains throughout the night. Waking up with my knees hurting, ankles hurting, etc. Can anyone out there tell me if they have had a spa and does it help with the Fibro?

Just getting in a hot tub helps me so I am sure a spa would be great, don't have one though. As for the night, I put a 2" memory foam pad on my mattress and it helps me not have pain or stiffness from sleeping.
