I am 28 year old female diagnosed with Hashimoto thyroiditis 2 years ago on thyronorm 75mcg and currently tsh 2. Anti ttg were normal. I am suffering from chronic intermittent lower abdominal pain (2 years)which is dull, sometimes with lower back, mainly starts after bowel moment, stays for few hours and goes away on its own till noon. But recently its been happening every month for 1 day qhole and then fades slowly on another day. No blood in stool. But bowel shape changes during this either bulky or mushy. Associated with abdominal distension. I also got operated for chronic fissure last year which was from 7 years and with anal spasm. My esr, crp is normal. Hb is 12.5.
