Hi Customer (name blocked for privacy), welcome to JA.
Primary focal hyperhidrosis refers to excessive sweating that is not caused by another medical condition, nor is it a side effect of medications. The excessive sweating is the medical condition. This type of sweating always occurs on very specific areas of the body (described as focal areas). The scalp is one common focal area, others include, palms, feet, underarms or face. (It is localized to one area to the exclusion of the others)
Hyperhidrosis is often misunderstood and underdiagnosed. The International Hyperhidrosis Society has a website offering information on the condition, treatment options, support, and Physician referral services. You can access their website at:
