Head aches and stomach issues

Hi, i smoked weed for 34 years, not heavy but one joint a night as sleep aid, with alcohol. I gave up at the start of my holiday 13 days ago and didn’t realise the impact of withdrawal. During the holiday i had most of the withdraw symptoms. But after a week i felt more mentally balanced and happier. However when i arrived back home i started to get real bad ear ache and head aches as well as bad stomach and digestive issues, im now on day 13, would this be still part of withdrawal? Thx
