High pulse, diarrhea, headache, helplessness and regret 4 days post op Tummy Tuck. (photos)

I'm so sorry to hear you are having such a rough recovery! While the early regret feeling can be a normal part of recovery, the rest of your recovery does NOT sound normal and I recommend you notify you surgeon and seek medical help now to make sure nothing serious is going on. It's worrisome that you say your heart rate has not come down from 120. A high heart rate can be pain related, but once your pain is under control, this should go down. Also, the diarrhea is also concerning, and the blood pressure is high. Normally dehydration alone would give you a low blood pressure and high heart rate. Also, most patients who are taking pain medication report constipation rather than diarrhea. It would be useful to know your past medical history (any history of high blood pressure, for example), if you are walking, tolerating food and liquids by mouth, and what your urine output was like to get a better picture of what is going on. Also, was the 2 day hospital stay for routine aftercare, or was that for a specific reason? Unfortunately I don't have enough information to determine what is going on, but I would highly recommend notifying your surgeon right away, and getting medical attention. If your surgeon is unable to see you right away, you may need to go to the emergency room for an evaluation. If you've been feeling dehydrated since surgery and having diarrhea, it may be helpful to check labs and look at your electrolytes, and you may benefit from IV fluids if you aren't able to tolerate liquids by mouth. The reason for the diarrhea also needs to be determined. You may need to be admitted to the hospital, so don't delay in getting medical care. It's always better to be safe.

The tachycardia is from the dehydration and the pain.  I would suggest that you need to get the diarrhea under control as well as the pain.

I'm sorry to hear about the problems you are experiencing.  I think that you need to seek medical attention now.  Your change in vital signs along with continuous headache and diarrhea are all signs of a potentially serious problem. Accurate diagnosis and treatment is necessary ASAP.   Best wishes.
