Ledum Palustre is a wonderfully versatile homeopathic remedy and very useful in the summertime especially after tick bites.
For the above indicated symptoms a 6C or 30C is helpful taken as needed up to 4x daily while symptoms persist.
Specific dosing recommendations can be given by a health practitioner.
Ledum 30C is included in the 36 Helios Remedy Kit for sale on my website. Link in bio.
