Odd Withdrawal Symptom

I was wondering if anyone else out there experienced what I experienced last night. I take nothing but the 7 oh tablets in the aqua colored package. I had not taken any since Saturday at noon. Generally I get hit with withdrawals within 24 hours of my last dose. I felt pretty decent at the 24 hour mark yesterday, just the usual runny nose and the feeling that I can't get warm. But I was able to do some laundry and make dinner, so I had high hopes that this time around, I would be okay.

I was really tired so I laid down around 7:30 and read for a little while until I started falling asleep. I was dead asleep for about 15 minutes when, out of nowhere, I felt what I can only describe as restless leg syndrome, only in my shoulders, arms, and upper spine. I only got comfort by moving, stretching my arms, and laying back down. Unfortunately, that comfort would only last for 10 to 30 seconds. This went on until 4:30 this morning when it just....stopped. I fell asleep for about 30 minutes until my alarm went off.

I have had similar symptoms when trying to quit before, only in my hips. Just like last night, I could only get seconds of comfort after moving my hips by spreading my legs, opening and closing, and rolling over. Sometimes I would put my foot on by footboard and push my whole body back and forth. This would help, but as soon as I fell asleep and stopped the body rocking, it would come back.

I know there's got to be someone else out there who has had this experience. As far as withdrawal goes, I would take these symptoms over the chilling, sweating, anxiety, depression, irritability, and other symptoms that would come when coming off other forms of kratom, but they are still aggravating.

Every type of kratom has its own set of withdrawal symptoms. I know this because I have taken shots, capsules, powder, vape pen (do not waste your money on that POS), and tablets.

TLDR: Has anyone else experienced ONLY restless arm/shoulder/spine?
