Inflammation (confirmed that there is no infection) 7 months after surgery

Your symptoms suggest that the surgical site may not be healing properly due to underlying issues like unresolved inflammation, foreign body reaction, or improper absorption of the internal sutures. Here's a breakdown of possible causes and steps to consider:
Possible Causes
1. Suture Granuloma or Foreign Body Reaction:
o Internal sutures that have not dissolved properly (or are being rejected) can cause inflammation, blistering, and discharge.
o The body may form a granuloma around the suture material, leading to repeated irritation and drainage.
2. Seroma or Fluid Collection:
o A pocket of fluid may have formed under the scar, leading to pressure and blister formation.
3. Wound Dehiscence:
o Partial reopening of the internal layers of the incision might cause chronic irritation and discharge.
4. Chronic Inflammation:
o Even without infection, prolonged inflammation can cause delayed healing and skin breakdown.
5. Underlying Scar Complications:
o Hypertrophic or keloid scarring, or scar instability, could cause blistering and poor skin integrity.
Next Steps
1. Seek Specialist Evaluation:
o Visit a wound care specialist, plastic surgeon, or dermatologist. They may have more experience with complications like yours.
2. Diagnostic Imaging:
o An ultrasound or MRI of the area can help identify any retained sutures, fluid collections, or underlying tissue abnormalities.
3. Biopsy:
o A small sample of the affected tissue may be taken to rule out granulomas, unusual scarring, or rare conditions like pyoderma gangrenosum.
4. Blood Tests:
o Testing for systemic inflammation markers might help identify if the body is reacting to foreign material or other triggers.
5. Management Options:
o Removal of Sutures: If the internal stitches are causing the issue, they may need to be removed surgically.
o Topical or Systemic Medications: Anti-inflammatory creams or oral medications may be prescribed to reduce irritation.
o Wound Care: A wound care plan, including dressings to manage blistering and discharge, may prevent further breakdown.
o Steroid Injections: These may help control inflammation or scarring in specific cases.
Your persistence in seeking answers is important. Make sure to track any changes, such as increased redness, worsening discharge, or systemic symptoms (e.g., fever), and report them immediately to your healthcare provider.
