Management of Blisters and Calluses in Tennis Players
For troublesome blisters in a tennis player, pierce the blister at its base with a sterile needle to drain the fluid while leaving the blister roof intact, then apply a non-adherent dressing; for calluses, carefully pare them down and focus on prevention through proper equipment and hand care.
Blister Management Algorithm
Intact, Pressure-Painful Blisters (Most Common in Tennis)
The British Association of Dermatologists provides clear guidance on blister management 1:
- Pierce the blister at the base with a sterile needle, bevel facing up
- Select a drainage site where gravity will prevent refilling
- Leave the blister roof in place - it acts as a biological dressing
- Gently apply pressure with sterile gauze to facilitate complete drainage
- Cleanse with antimicrobial solution after draining
- Apply a non-adherent dressing
- Large blisters may require multiple puncture sites for adequate drainage
Critical caveat: Do NOT deroof intact blisters - the roof provides natural protection and reduces infection risk 1, 2.
Already-Ruptured Blisters
- Without infection signs: Leave remnants of the blister roof in place
- With infection signs (redness, warmth, purulent drainage): Remove the blister roof completely and consider topical antimicrobials 1
Pain Management
Many patients experience significant pain during blister care - offer analgesia before the procedure 1. This is particularly important for athletes who need to continue training.
Callus Management
For troublesome calluses on tennis players' hands 3:
- Carefully pare down the thickened skin (avoid aggressive removal)
- Apply emollients regularly to soften tissue
- Consider this a maintenance issue requiring ongoing attention
Prevention Strategy (Critical for Athletes)
Equipment Modifications
- Proper racket grip size: Ill-fitting equipment increases friction forces 4
- Overgrip application: While one study showed no significant association with injury prevention 5, clinical experience suggests fresh overgrips reduce friction
- Consider grip tape or glove use during high-volume training
Skin Preparation
The evidence on friction reduction is mixed, but practical approaches include 4:
- Lubricants applied to high-friction areas before play (reduces friction coefficient)
- Keep hands moderately dry - both very wet and very dry skin increase blister risk
- Avoid antiperspirants with emollients - they don't reduce blister incidence
Hand Conditioning
- Gradual exposure to training loads allows cellular proliferation and epidermal thickening 4
- Most blisters occur at season start or position changes when hands are "unconditioned" 6
- Progressive volume increases are protective
Ongoing Hand Care
Apply the "soak and smear" technique nightly during problem periods 7:
- Soak hands in plain water for 20 minutes
- Immediately apply bland emollient (50% white soft paraffin/50% liquid paraffin) to damp skin 1
- Consider cotton gloves overnight to create occlusive barrier
- Continue for up to 2 weeks
Return to Play Considerations
For competitive athletes, timing matters:
- Drained intact blisters: Can typically return immediately with proper dressing
- Infected blisters: Require 72 hours of antibiotic therapy with no new lesions for 48 hours before competition 8
- Hydrocolloid dressings provide pain relief and may allow continued activity 4
When to Escalate Care
Seek medical evaluation if:
- Signs of infection develop (increased pain, redness, warmth, purulent drainage)
- Blisters become recurrent despite preventive measures
- Underlying dermatitis develops from repeated trauma
Important note: The evidence shows that 69% of competitive rowers accept calluses as normal 6, and tennis players similarly develop hand adaptations. The goal is managing symptomatic lesions while allowing protective tissue development, not eliminating all calluses.
