The title appealed to me as I have a friend who does Acupuncture. What a unique and interesting topic for a poem. You really were able to capture the main process and the experience of having it done. I got the idea that you have recieved it or have first hand information about it. The point of view here is positive and that the modality indeed beneficial. Your last line was evocative and I could imagine the body's joy at having released some stress. It gives readers, who may cringe at the idea of needles in the skin, a peek at the healing outcome.
The poem was fun to read and had a lively vibe.
Your imagery and description of the process was detailed and so vivid, highlighting the "muscles". The vocabulary suited the theme and I liked the active expressive words like "jostle", "pulses" and the idea that the body screams for more. It is a cool notion when usually we think of screams for painful things.
The words flowed fairly smoothly though the rhythm count was not even. It shows effective use of rhyme, though I notice off rhymes there, not sure of pulses and doses but the 's' sounds mimic the idea. Some assonance and consonance to create a pleasing soundscape. Punctuation assisted the read though I think a comma after "still" in line 4 and after "thin" in line 1 would help with the reading there. That line was a little unflowy to read. I wanted to say" silver, pointed, thin, lite as air." The and seems to slow it down and puts thin and lite at conflict with ease of flow.
I know this is a CRAMP item so Wow, what a great job in a short time. I really enjoyed your happy vision.
Highest regards and Light on the path as you Write on!
