The Cupping Thearpy

I ate too many much ice creams and cold food recently, which lead made my tummy uncomfortable, and it's nearly rainy day for a period [I'm not sure what you meant about the rainy day]. So I decided to have a cupping therapy therapy. 
I have never done that before. I am was curious about it. But it really ached when the cupping jar touched your my skin.  [Or, "But it really aches when the cupping jar touches your skin.] Oh, there were nine cupping jar I have.  [I'm not sure what the sentence means.  Do you mean "They put the cupping jar on my body in 9 places"?]
When time went, it would feel good. [Maybe you mean:  After a while, it felt good] If you have back ache, you will definitely feel awesome.
Well The cupping therapy therapy will make some blood stasis [??] in your boody, so it  you will still have pain. The therapy therapy needs to be done by professional people to do .So do not try it by youself. Because it involves acupoints , and you can't accept do it when you have some body questions [maybe you mean:  "you can't do it yourself unless you understand anatomy"]
