Ions deficiency is possible.
Thank you for the query.
Muscle twitching can be caused by ions deficiency (low Magnesium
, Potassium, Calcium). As a Crohns patient you may have such deficiency as not everything is well absorbed.
You should also know that with Crohns disease
joints, skins or muscles inflammation due to autoimmune process are also possible. So if you have any joints swelling/redness
with this muscle problem, you should consult your doctor or rheumatologist
I suggest you to try some Magnesium 400 mg with Potasium supplementation. This should help. If not, please have ions levels checked.
Hope this will help. Feel free to ask further questions.
