Hi, smoked Marijuana socially over many years and daily for four years before giving up three weeks ago. Have tender neck, right side which comes and goes and pain in shoulders again that comes and goes, often more at night. Also some headaches. Had discomfort in right lung while smoking but this has pretty much abated now. Was having a lot of acid reflux but this also is not occurring much now. Hoping the shoulder and neck pain will go over time. I am 1.95m tall, 100kg and 52 years of age. Your thoughts? Thank you.
