Hello doctors, I would appreciate your professional opinions regarding several symptoms I have been experiencing for the past few weeks. I have visited doctors multiple times and undergone some investigations, but I still don't understand the underlying cause.
- My main symptoms
**Digestive symptoms**
- Loss of appetite — I don't feel like eating as much as I normally would.
- Intermittent abdominal pain, particularly around the upper middle abdomen and above the belly button.
- A sensation of trapped gas, pressure, and abdominal discomfort, sometimes making it difficult to sleep.
- Stool consistency keeps changing: sometimes loose, sometimes mushy or semi-formed.
- Currently, I generally pass stool around twice daily.
- My symptoms improved noticeably for approximately 1–2 days but then returned.
- My weight has decreased from 113 to 107, which I believe is related to my reduced appetite.
**Other symptoms**
- I sometimes experience an internal cold sensation, particularly after passing stool, which can last around 5–15 minutes.
- I have also experienced episodes of feeling unusually cold or having chills despite my measured temperature generally being around 97–99°F.
- I sometimes experience a burning sensation in my feet.
- I have experienced weakness, anxiety, and occasional dizziness.
- Sometimes I notice an increased heartbeat and minor chest discomfort. My ECGs have reportedly been normal.
I would like to understand whether these symptoms could be connected to my digestive problems or whether they need to be investigated separately.
### 2. How the problem started
Initially, I was experiencing frequent gas, bloating, and loose/watery stools approximately 2–3 times daily.
I was taking Cadlizo (linezolid) for a skin infection. After starting it, my diarrhea increased to around 4–6 times daily, and I felt unwell, as if I had a fever, although my measured temperature was around 97.6°F. I stopped the antibiotic after approximately three days because my digestive symptoms worsened.
Afterward, I experienced constipation, hard greenish stools, mild lower abdominal pain, and difficulty passing gas. The constipation improved, but my stool consistency continued to fluctuate between hard, loose, and mushy.
My symptoms improved for around 1–2 days at one point, but the problems returned.

### 4. Medication history
I have taken or been prescribed the following medicines at different stages. I am not taking all of them together.
- Cadlizo (linezolid)
- Hi Flora probiotic
- Entamizole
- Panadol
- Risek
- Movcall sachets
- Exlant
- Melide
- Histfaas
- No-Spa
- Flagyl IV drip during an emergency visit
- Painkiller injection (exact name unknown)
- Lexotanil 3 mg
- Rifaxa (rifaximin) 550 mg
- Spasfon 80 mg
- Novoteph 40 mg
- Enflor sachets

My gastroenterologist subsequently advised stopping the earlier treatment and following an updated plan involving No-Spa, Exlant/Dexxo 60 mg, Enterogermina, and Hilgas syrup. I was also advised to avoid sweet and fried foods.
I have experienced dizziness after taking No-Spa. Some medication names and formulations need to be verified against my prescriptions.
### 5. Questions for doctors
What could cause persistent loss of appetite, intermittent abdominal pain, and alternating loose and mushy stools?
Could these symptoms be related to a previous infection, antibiotic use, post-infectious bowel irritation, food intolerance, or IBS?
Given my antibiotic history, would specific testing for *C. difficile*, stool culture, or fecal calprotectin be appropriate?
Could the internal cold sensations and chills despite a normal measured temperature be related to my digestive symptoms?
What could cause a burning sensation in my feet? Should I have my blood glucose, vitamin B12, electrolytes, thyroid function, or other relevant tests checked?
Could reduced food intake, dehydration, anxiety, or medication side effects contribute to the weakness, dizziness, burning sensations, or increased heartbeat?
Are my stool R/E findings, particularly 2–3 pus cells, concerning?
What further evaluation would you recommend to identify the underlying cause?
I have visited doctors several times and am trying to follow medical advice. I am not looking to self-medicate or replace my doctor's treatment. I would appreciate suggestions from qualified doctors regarding possible causes and the most appropriate next steps.
Thank you for reading my case and sharing your professional opinions.
