<s>[INST] Hi, I am a 45 year old female with 2 teenagers. Still menstruating and not sexually active. My tummy has been jumping involuntarily for around 2 weeks. Its worse wen lying down. Its not painful and bowels are normal. Its forceful and feels like late pregnancy baby kicking but Im definitely not pregnant. [/INST] Hi. Thanks for your query. This is quite a rare thing to have. This may be a muscular twitching. The cause is not known. And there is no definite treatment. It would be better to be seen by a Surgeon, who would rule out internal problem by clinical examination and may be some investigation if he feels so. Also check for serum electrolytes, as dis-balance may cause such feeling. Occasionally medicines alike amitriptyline may help, but you need a prescription for this and such medicines from your Doctor. </s>
